Nikki Reed will star in 'The Sunday Horse'.
The 'Twilight' star has been cast in the film which is based on the true story of equestrian rider Debi Connor who overcomes the odds, and a near-fatal accident, to win the U.S. championship on a horse saved from slaughter, reports deadline.com.
BAFTA-winning 'Left Behind ' director Vic Armstrong is set to helm the project, while Fred Kuehnert will pen the script and Ronnie Clemmer is on board to produce alongside John Duffy.
'The Sunday Horse' is scheduled for a 2015 release.
Meanwhile, Reed - who was catapulted to the spotlight in 2003 following the release of 'Thirteen' - is reportedly dating Derek Hough after announcing she split from husband Paul McDonald in March after two years of marriage.
The 25-year-old actress was spotted making out with Hough, 28, at Rock & Reilly's in Los Angeles last month, while they were enjoying a night out with friends, including Mark Ballas and Cheryl Burke.
An eyewitness previously said: "The whole group was drinking and partying. Derek bought shots for Nikki at the bar. There was lots of PDA, Nikki was feeding him, holding hands, and they left together. They didn't seem to care if anyone was watching."

Arnold Schwarzenegger is glad he's not an actor who is "over the hill".
The 66-year-old star - who hits the big screen in 'Sabotage' - is delighted his age hasn't prevented him starring in Hollywood blockbusters.
Schwarzenegger says: "I feel very honoured that I'm not looked upon as some old guy who is over the hill. That can happen to actors very quickly."
Although the hunk is best known for his action roles he was cast in comedy 'Triplets', which is the sequel to 1988 film 'Twins', and was set to star alongside Danny DeVito and Eddie Murphy.
Meanwhile, Schwarzenegger will reprise his role as the titular cyborg in 'Terminator: Genesis' after he was forced to step down from participating in the franchise while he was the Governor of California between 2003 - 2011.
He "never thought" he would be asked to be in these productions, especially "unusual" comedy films.
Schwarzenegger told The Sun newspaper: "I never thought that all of the studios would come back and ask me to play these characters again.
"To play the 'Terminator' again, or to ask me to do 'Triplets' with Danny DeVito and Eddie Murphy, is very unusual."

Usher has recorded a collaboration with Chris Brown.
The 'Good Kisser' singer has confirmed the troubled R&B star - who is currently serving a prison sentence for violating the terms of his probation, stemming from a 2009 assault on pop star Rihanna - will feature on his upcoming eighth studio album and it seems the track will reflect on Chris' recent troubles.
Usher told Revolt TV: "The song that we did together, I think it answers a lot of questions. There's a lot mystery, I think, about a lot of things and the reality is we all are human. And though we may all experience hardship, it's in those times that people should really rally and remember why you fell in love with the artist, why you fell in love with the person."
The 35-year-old star admits he hasn't had a chance to talk to Chris, 25, since he was imprisoned, but says the 'Loyal' singer was in a "good place" after leaving rehab for anger management issues in February.
He added: "We have not been able to talk, but when he first came out of rehab, there was a lot of conversation back and forth and he was in a really good place, good positive place."
While Chris is expected to remain in prison until June, his latest single 'Loyal' - which was released shortly after he was jailed - has enjoyed success in both the US and UK singles charts.
However, plans to release a duet with pint-sized singer Ariana Grande had to be put on hold following his imprisonment.
Chris and Ariana had recorded a music video for 'Don't Be Gone Too Long' and begun a countdown to the song's premiere in the days before he was incarcerated.

Madonna claims producer Diplo is a "slave driver" in the studio.
The 'Hung Up' hitmaker is making music with Katy Perry's rumoured boyfriend and admits he pushed her to her limits when the pair teamed up together.
Madonna posted a photograph of her on a laptop on her Instagram account, with the caption: "Working with @Diplo got me like................WHAAaaat? (sic)"
She later added a photograph of herself looking tired after a long session working on new ideas and wrote: "Diplo is a slave driver! Got me working all hours of the night in the studio. Had to sneak into the bathroom! #clicclacclicclacbitchgetoffmyback (sic)"
Diplo, who has had success with his electronic music project Major Lazer, has previously worked with the likes of Beyonce, Rita Ora, Tinie Tempah and Justin Bieber and is known for his reggae-inspired music.
Meanwhile, Madonna has also been in the studio with dance music star Avicii, who produced Coldplay's new single 'A Sky Full Of Stars' and she's set to release new material in coming months.

Ali Campbell is thrilled to be reunited with original UB40 member Astro and "flying the flag for reggae again".
The 55-year-old star is back recording with singer-and-rapper Astro who joined Ali and keyboard player Mickey Virtue in January 2014 to reform as UB40.
Astro quit the other incarnation of UB40 - comprised of original musicians but with Ali's brother Duncan Campbell on vocals - after becoming disillusioned with their musical direction following the release of their country album 'Getting Over the Storm' saying it wasn't "something he wanted to be a part of".
Ali is thrilled to be working with Astro again and has promised fans they will be performing pure reggae when they head out on tour to perform with the classic UB40 hits being sung by the legendary vocalists who recorded them.
Talking about his reunion with Astro, the 'Red Red Wine' hitmaker said: "Basically, after UB40 the oldsters made a country album which was a total slap in the face to me, to the fans and to Astro, he came back with me and Mickey - who left with me when I left nearly six years ago now.
"Astro had left and asked if he could join with me, I said, 'Yes.' So we did our first show at the IndigO2 in London in December and the reaction was so good we thought, 'F**k it. Let's get back together again.' We call ourselves UB40. We're back flying the flag for reggae again."
Ali has also criticised his former band - which also includes his other brother Robin Campbell - for touring under their original name but not stating that he has been replaced as the singer.
The 'Can't Help Falling in Love' singer - who left the group in acrimonious circumstances in 2008 - told BANG Showbiz: "All along the line I've been saying, 'Its Ali Campbell's UB40', or 'The Legendary Voice of UB40 Ali Campbell'. So that people knew who they were getting. Now, UB40 the old boys haven't done that once in six years; they haven't said, 'Not original line-up.'
Ali is currently putting the finishing touches to a new album with Astro and Mickey and he can't wait for people to hear it because it is a classic sounding UB40 reggae record.
Talking about the album, he revealed: "The new album is 100 percent reggae, I know the fans are going to love it because it sounds like a UB40 LP ... That'll be out soon on Cooking Vinyl."
UB4O - Ali, Astro and Mickey - will be touring the UK in December with dates in Birmingham on December 19, London December 20 and Manchester December 21. For tickets and information go to Kililive.com.

Britain's Duchess of Cornwall has made her first public appearance since her brother's funeral.
Camilla put on a brave face yesterday (08.05.14) at the opening of two medical centres for the nation's armed forces, just one week after her brother Mark Shand was laid to rest.
The 62-year-old conservationist tragically passed away last month after sustaining a head injury during a fall in New York. His memorial was held at Holy Trinity Church in Stourpaine, Dorset, on May 1.
The duchess began her official duties at a Royal Air Force base in Leeming, North Yorkshire, where she was greeted by a crowd of eager schoolchildren ahead of opening a £5 million medical centre.
She then headed to open the new £138 million medical training headquarters at the Defence Medical Services Whittington in Staffordshire, where she undertook a tour of the facility and witnessed a special dedication ceremony.
According to the Lichfield Mercury, Camilla said during her speech: "It gives me enormous pleasure to be with you all here today, at Defence Medical Services Whittington, for the dedication of this new, state of the art, medical training facility, which, I know, so many have worked so hard to bring to fruition over the last few years...
"I have seen for myself how tirelessly those in all three medical services strive to achieve the highest possible standards, and I am certain that with the training available here, our Forces will continue to receive the very best medical support."
Before jetting back to London by helicopter, the 66-year-old royal unveiled a commemorative plaque and cut a celebratory cake with Pte Ryan Benson, the youngest person serving at DMS Whittington.

Ola Jordan is returning to 'Strictly Come Dancing'.
The professional dancer is said to have signed up to star in the new series of the BBC One ballroom dancing contest, despite reportedly threatening to quit last year because she felt "bullied" by fellow dancer Karen Hauer.
Her husband and co-star, dancer James Jordan, is expected to follow suit.
A source told The Sun newspaper: "Losing her would have been a blow. Now they hope James will follow her lead."
Ola's spokesperson revealed she had been "verbally attacked" and deeply upset during a showdown with Karen last November, with the brunette allegedly branding her a "rubbish dancer".
Show bosses forced Karen to apologise to Ola after the incident, but the 31-year-old blonde's future on the show was left on uncertain terms.
James then posted a cryptic message on Twitter last December, calling for a shake-up of the current judging panel, made up of Len Goodman, Bruno Tonioli, Craig Revel Horwood and Darcey Bussell.
He wrote: "Maybe instead of always looking to change the amazing pro dancers. I think it's about time they have more judges from the ballroom world!"
A 'Strictly' spokesperson has claimed this year's professional dancer line-up has yet to be finalised.
They said: "Discussions are on-going with all professional dancers for Strictly's next series, and the line-up will be announced in due course."

Hugh Jackman has been treated for skin cancer again.
The 'Wolverine' actor - who had cancerous cells removed last November - has urged fans to protect themselves from the damaging rays of the sun after undergoing a proecudure to remove a Basel Cell Carsinoma (BCC).
Posting a picture on Instagram showing his bandaged nose, he wrote: "Another Basel Cell Carsinoma. All out now. Thanks Dr. Albom and Dr. Arian. PLEASE! PLEASE! WEAR SUNSCREEN! (sic).
"Huge thanks to Dr. Arian and Dr. Born for operating on my nose until 10:20pm! #SUNSCREEN (sic)"
BCC is a treatable and common form of skin cancer signified by lesions or growths on the outermost layer of the skin that "often look like open sores, red patches, pink growths, shiny bumps, or scars" and are "usually caused by a combination of cumulative UV exposure and intense, occasional UV exposure, the Skin Cancer Foundation says.
Although it generally doesn't spread, the organisation warn that it can be disfiguring if not treated quickly.
The 45-year-old actor was first treated for the disease last year after wife Deborra-Lee Furness - with who he has children Oscar, 13, and Ava, seven, - urged him to get a "mark" on his nose checked out.
He tweeted: ''Boy, was she right! I had basil cell carcinoma.
''Please don't be foolish like me. Get yourself checked. And USE sunscreen!!! (sic)''

Angelina Jolie says taking her children to work made her "stressed".
The 'Maleficent' actress and her fiance Brad Pitt agreed to allow their six kids, Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and twins Vivienne and Knox, five, to visit them while making movies, but wanted them to have an honest portrayal of what life is like on a film set.
However, after just two days with the kids close by, the couple wanted the children to find new ways to entertain themselves.
She said: "Brad and I made the decision that we wouldn't keep them from sets and the fun of making movies, but we wouldn't [glorify it either].
"We wouldn't make it a good thing or a bad thing. But I would really prefer they do something else. After two days of it, Brad and I were so stressed we never wanted to do it again."
Angelina's youngest daughter appears in 'Maleficent' as young Princess Aurora and the actress thought she was perfect for the role as Vivienne is so devoted to her, she wouldn't be intimidated by her scary character.
Angelina explained to the new edition of America's Elle magazine: "For young Aurora, they needed a child who wouldn't be fazed by the Mistress of All Evil hissing, 'I don't like children' in her face.
"And my little Vivienne - we call her my shadow, because there's nothing I can do to shake her. I can be tired, I can be grumpy, I can be in a terrible mood, and she doesn't care. It's 'Mommy, Mommy,' and she'll cling to me.
"We knew that she would still do that thing, she'd still smile at me and insist that I pick her up. So we couldn't really cast anybody else."
The role was initially offered to the couple's older daughter Shiloh, but the tomboy insisted she would rather play a "horned creature" instead.
Angelina added: "I asked Shiloh about being Aurora, and she laughed in my face."

Courtney Love turned down a night with Russell Brand.
The 49-year-old rocker - who was famously married to late Nirvana frontman Kurt Cobain until his death in 1994 - has claimed she spurned the comedian's advances because of his "musky" stench.
Appearing on British talk show 'Alan Carr: Chatty Man', which airs tonight (09.05.14), she recalled: "When we were friends, he tried to hit on me. He goes, 'I have had a lot of grand conversations, darling, but none of them have ended in an orgasm. Can we go in a room?'
"I said to him, 'Russell, you are too musky for me, man.' He is a little musky. We did yoga together and the musk was there."
While Courtney refused to be a notch on Russell's list of sexual conquests, the pair remain friendly and she even thinks of him as a British "national treasure".
The star added: "I do think he is a national treasure. God, I wish I was as good as him. He flirts with men openly too."
While the Hole singer wasn't won over by Russell, she has previously fallen for the charms of another British comedian, 'Alan Partridge' creator Steve Coogan, admitting she was smitten with him because of his portrayal of Factory Records boss Tony Wilson in 2002 movie '24 Hour Party People'.
Speaking some time after their fling, she has previously said: "All it was, was a couple of sh**s at the Sunset Marquis [hotel in Los Angeles,] and I did not know he was Alan Partridge.
"I thought he was Tony Wilson in '24 Hour Party People' - somebody I'd always had a daddy thing for. I had never seen 'Alan Partridge'. But I was in a band with people who did know about Alan Partridge, so I had to make a record with them constantly saying to me, 'Back of the net!' "
Russell, 39, was wed to 'Roar' hitmaker Katy Perry between 2010 and 2012, and is currently dating Jemima Khan.

Noel Gallagher's daughter has secured her first job as a TV presenter.
The 46-year-old rocker's 14-year-old daughter Anaïs, from his first marriage to interior designer Meg Matthews, has been hired by UK children's channel CBBC to present the 'Friday Download' series, giving advice on fashion and style to viewers.
A source told The Sun newspaper: "Bosses see great potential in Anaïs. She auditioned and was an instant hit.
"Anaïs is a quick learner and very natural on screen. Of, course her connections played a part."
The aspiring TV star will join a number of other young presenters on the show, including 18-year-old singer Dionne Bromfield, who will return for a second series.
Anaïs mother is said to be encouraging her daughter to pursue a career in television, and CBBC are reportedly keen to help the youngster to become a regular face on the network.
The sourced added: "All going well they could develop her within the company as a future star.
Although Anaïs has no previous television experience, the young blonde has worked as a presenter for fashion store Claire's Accessories' website, which involved filming alongside 'Wild Heart' hitmakers The Vamps.

Antonio Banderas says fighting comes "naturally" to him.
The 53-year-old actor, who plays Galgo in 'The Expendables 3', insists it was easy for him to slip into character and his love of sport helps in action roles which require "certain abilities".
Talking to collider.com, he explained: "I have a rifle, and I use a lot of fighting skills that I learned years ago. I tried to do as much as I could. I have certain abilities. I think I am good in the department of body language and fighting, and stuff like that.
"It's just natural to me, maybe because I love sports. As long as you have a good choreographer for that, and we did, it's relatively easy to get into that world, for me."
Banderas admits he questions the roles he gets as he ages but, at the same time, he enjoys taking on the challenge.
He added: "You have to be in good shape, basically. And then, you have to have a certain craziness, if you're going to do some of the action things. I did something that I shouldn't have done. I'm in my 60s now, and just running almost 50 meters with explosives going on, it was kind of like, 'Oh, my god! What am I doing here?' The whole entire building was shaking, and stuff like that.
"But, you do it. At the same time, I just wanna do it if I have the possibility of laughing a little bit at myself."
