Margot Robbie is dying her hair for the new 3D version of 'Tarzan'.
'The Wold of Wall Street' actress recently went from blonde to brunette for another movie role and is in the process of changing it back to star alongside 'True Blood' hunk Alexander Skarsgard in the upcoming Warner Bros. film.
She told ITN News: "We start in a couple of months. I got the script, loved it, met with David Yates, the director, I loved his vision and all the pieces came together. I got picked for the role ... [I'm] very lucky.
"I just did a film where I had brown hair, it was manky brown, awful, but it was meant to look like that in the film. We made it a nicer, richer colour for the Oscars but now I have to go lighter again for 'Tarzan'."
She added: "I don't think blondes have more fun though ... people always ask me that but I love this colour."
The 23-year-old star also plans to stay in shape for the jungle film by mixing pilates with ballet, which she has been doing during her time in Los Angeles.
She explained: "I just posted a picture on Instagram from Ballet Bodies, where I have a trainer, it's like pilates with ballet techniques. I love it."
Talking about her rise to fame after staring in 'The Wolf of Wall Street', alongside Oscar-nominated actor Leonardo DiCaprio, she said: "It hasn't changed too many things, I'm just a lot busier, which is a wonderful problem. I'm really lucky and getting the chance to work with people I really want to work with, it's amazing."
Margot admits she was disappointed Leonardo didn't win an Oscar for Best Actor for his role in the film but insists he handled it well.
She said: "He's such a humble guy, he would never be a bad sport about those things. I think he's just grateful to be there and nominated, he doesn't have a big ego, despite his big profile."

The Four Tops star Duke Fakir believes Diana Ross and Mary Wilson are set to reunite for a concert as The Supremes.
The 78-year-old singer thinks the time could be right for the two stars to put their differences aside after so many year and put the iconic Motown group back together one last time with Cindy Birdsong.
Duke - who is the last original surviving member of The Four Tops - told BANG Showbiz: "I'm going to make a prediction; somewhere down the line I see her and Mary giving each other a big hug and saying, 'Let's do this one more time.' The older you get as you look back, whatever happened in those bygone days is forgotten - usually. Why not? I kind of feel that might be coming up. I think they might do one big concert or it could be a residency in Las Vegas or somewhere like for a week or so. It's very possible, I just see that happening and it would be great."
Duke - who is currently on tour in the UK with his group and The Temptations - is convinced that Diana, 70, is ready to bury the hatchet with 70-year-old Mary and knows she is ready to perform because she regularly performs, describing her concerts as "fantastic".
Temptations star Otis Williams is also hopeful for a reunion and insists the 'Baby Love' hitmaker is in a position where she can play just to cement her amazing legacy.
Otis, 72, said: "Oh Mother Supreme, as I call her, is still playing. She's in a unique position where she can keep playing and work when she wants to work."
Mary turned down the chance for a reunion tour as The Supremes in 2000 after she discovered Diana was offered $15 million to do it, whilst she was offered $4 million and Cindy less than $1 million.
The last time Diana and Mary appeared on stage together was on the 'Motown 25: Yesterday, Today, Forever' TV special in 1983.
The Temptations and The Four Tops - joined by special guests The Platters and Freda Payne - are playing concerts across Britain this week, including Manchester Arena tonight (02.04.14) and The O2 in London on Thursday (03.04.14).

Charlie Sheen's ex-wife "adores" his new fiancée.
The 'Anger Management' star's former spouse Brooke Mueller, with whom he has five-year-old twin boys Bob and Max, is thrilled he is marrying former porn star Brett Rossi because they get on really well.
A source told gossip website RadarOnline.com that the 36-year-old socialite, who has been to rehab for cocaine addiction more than 20 times, is "ecstatic over Charlie's choice for a future wife."
The insider said: "She is so happy. Brooke has repeatedly been over to Charlie's house with their sons, Bob and Max, and she and Rossi have truly hit it off.
"Brooke has even chided that Charlie is an amateur compared to her and she would 'pinch hit' for Charlie with Brett in a second if she got the chance."
The source added: "Brooke loves the current environment of Rossi's support and the bond all of them are creating while she resides in a house Charlie bought her which just down the street. This is a dream come true for Brooke and the boys since they have Brett and Charlie as neighbours and they are all getting along and truly liking each other."
Brooke was previously locked in a bitter custody war with Charlie and his second ex-wife Denise Richards.
The 48-year-old actor "excommunicated" Denise in December, claiming she wouldn't allow him to see their daughters, Sam, 10, and Lola, eight.
Charlie proposed to his 24-year-old girlfriend on a Valentine's Day trip to Hawaii but their wedding is currently on hold as she is yet to finalise her divorce from her first husband, Jonathan Ross.

Rose McGowan is being sued by a DJ, who claims he was hired to play at her wedding.
Nahchey Storer has filed a lawsuit in the small claims court, claiming the 40-year-old star, who tied the knot with Davey Detail in Los Angeles last October, owes him $4,262 despite cancelling him before her big day.
The DJ says he had a written contract with the former 'Charmed' star and wants to be paid in full because she only told him not to come at the last minute, according to gossip website TMZ.com.
A spokesperson for Rose has yet to comment on the dispute.
Rose and Davey married in an outdoor ceremony at Paramour Mansion in front of 60 guests after more than a year of dating.
The actress revealed in September that she had hired a band to perform at their wedding when she announced details about their wedding.
She said at the time: "We're getting married October 12th at a mansion. It used to be a nunnery, so it's perfect for me. As everyone knows, I am a nun!
"I'm having a New Orleans swing band -- a brass band from New Orleans. I found them on the street."

Wiz Khalifa claims Miley Cyrus "smokes a ton" of marijuana.
The 26-year-old rapper, who was arrested for multiple drug charges in 2010, recorded several songs with the former Disney star for his new album 'Blacc Hollywood' and admits he was surprised by how much they have in common.
The 'We Dem Boyz' hitmaker told 'The Arsenio Hall Show' on Monday (30.03.14): "I got some songs with Miley on there."
Asked what it was like to work with the 'Wrecking Ball' singer, 21, he said: "Insane! But in a good way though, she's just a ball of energy. She smokes a ton."
Wiz, who has 13-month-old son Sebastian with his wife Amber Rose, claims he couldn't keep track of how much Miley was smoking.
He explained: "I don't know. She's younger so it's different. Every five minutes she kept being like, 'Hey Wiz, you don't have a joint rolled? What's up?' She was just blowin' like a train."
The 'Adore You' singer has frequently admitted she is a big fan of the drug in the past.
The controversial young star previously said: "I think weed is the best drug on earth! One time I smoked a joint with peyote in it, and I saw a wolf howling at the moon."
Wiz and Miley have a close friendship as his wife was previously managed by the singer's mother, Tish Cyrus.

Demi Moore wants to "reinvent" herself and reignite her acting career.
The 'LOL' actress, 51, embraced a "reclusive lifestyle" after seeking treatment in rehab following her split from ex-husband Ashton Kutcher in 2011, amid rumours he cheated on her, but is eager to take on more roles and connect with her fans again.
A source told gossip website RadarOnline.com: "Demi is loving her new reclusive lifestyle because she realises how overexposed she was when she was with Ashton. Now there's a real demand for her. She's learning that female fans really identify with her and hate the way Ashton behaved."
The 'The Joneses' star, who has daughters Rumer, 25, Scout, 22, and Tallulah, 20, with her ex-husband Bruce Willis, has reportedly embarked on a new diet and exercise regime ahead of her comeback and is planning to be very open about her personal struggles in recent years.
The insider said: "Demi is insisting on laying low ... [until] the fall. And she plans to re-emerge with a message. She is reinventing herself and that includes her look. Her new catchphrase is, 'Be honest- about everything!' It's a new approach her fans are sure to love!"
Demi has been linked to a number of men since splitting from Ashton, who is gearing up to welcome his first child with fiancée Mila Kunis later this year.

Solange Knowles' son has inspired her to be a "better person."
The singer, who recently admitted she feels "far older" than 27, has nine-year-old son Julez with her ex-husband, Daniel Smith, and has changed a lot since becoming a mother.
The 'Losing You' hitmaker told the May issue of Essence magazine: "Seeing that conviction and honesty with everything he does absolutely has made me a better person."
The star, who is Beyoncé's younger sister, added: "Motherhood is such an evolving journey. You really have to shape and mould your morals and values around that personality that has come into itself."
Solange, who is in a relationship with video director Alan Ferguson, previously said she doesn't want her son to follow in her footsteps and be a performer.
She said: "It's certainly not what I have in mind for him, I'm constantly trying to push him to work at the U.N., or be a diplomat. I try to convince him by explaining that he wouldn't have to wait in lines at the airport, and that he can park anywhere."
The singer is still on good terms with her ex-husband, whom she married when she was just 17 and divorced three years later.
She said: "We co-parent really well. I'm able to say, 'I need to finish this album, can you step up and take care of the boy?' "

Rachel Stevens has given birth to another baby girl.
The former S Club 7 singer, 35, and her husband Alex Bourne, who also have three-year-old daughter Amelie, welcomed their second child into the world on Tuesday (01.04.14).
Alex proudly announced the news on Twitter, writing: "Delighted to announce the safe arrival of our gorgeous little girl! @MsRachelStevens and baby both really well. Amelie happy and 'cited (sic)"
The couple, who have yet to reveal their newborn baby girl's name, also released a statement saying: "We're so happy that baby has arrived safely. Within minutes of meeting her we were totally smitten. Amelie is happy and 'cited to have a little sister to play with and we can't wait to introduce her to the whole family."
Rachel first confirmed she was pregnant again in September, tweeting: "Alex and I are so happy to find out that we are pregnant again and can't wait to meet our new little member of the family early next year.
"Needless to say, we're all super excited, especially Amelie who is looking forward to meeting her new little brother or sister."
The brunette beauty, who married Alex in 2009, previously revealed they had found out the sex of their baby but kept it a secret until her arrival.

Kelly Osbourne has reportedly gained 19 pounds since splitting from her fiancé.
The 'Fashion Police' co-host is said to be following a strict new diet and exercise regime in a bid to slim down again, after putting on weight since her break-up from Matthew Mosshart in January.
A source told Now magazine that the 29-year-old star, who lost 70 lbs. after appearing on 'Dancing With the Stars' in 2009, is currently on a healthy "cleanse" and wants to get her pre break-up figure back.
Kelly dated the vegan chef for more than two years after meeting him at Kate Moss's wedding in 2011 and recently admitted she wants to stay single for a "very long time."
She said: "I plan on being single for a very, very long time. No, I don't think it's possible for someone to sweep me off my feet right now."
The star was also previously engaged to model Luke Worrall and isn't sure if she ever wants to get married.
She said: "I'm really enjoying my life ... I don't now if I will ever get married. I think my views on marriage are changing, as I get older - not out of heartache, it's just that the world is changing.
"But if I ever do get married, I'm never changing my last name."

Kristen Dunst likes to have a "knight in shining armour" on standby.
The 'Two Faces of January' actress, who previously dated Jake Gyllenhaal and is currently in a relationship with Garrett Hedlund, admits she enjoys letting the men in her life take control sometimes.
The 31-year-old star told the May issue of Harper's Bazaar magazine: "I feel like the feminine has been a little undervalued. We all have to get our own jobs and make our own money, but staying at home, nurturing, being the mother, cooking - it's a valuable thing my mum created. And sometimes, you need your knight in shining armour. I'm sorry. You need a man to be a man and a woman to be a woman. That's why relationships work..."
The blonde beauty formed a close bond with her co-star Viggo Mortensen on the set of their upcoming film, but was initially "a little scared" to work with the 'Lord of the Rings' star.
She said: "He's surprisingly hilarious. The first time I met him, he was very reserved. It was in an elevator. I was like, 'Hi.' He was like, 'Oh, hi.' I learned later he was very shy. So I was nervous, even a little scared, to work with him. I thought, 'This is going to be intense.' Then I got the whole other side, which I don't think many people know. He should do comedy, I've told him that... I'm sure he wouldn't be happy with people knowing how fun he is."

Keira Knightley cheered on James Righton as his band kicked off their new tour.
The 29-year-old actress was spotted supporting her husband's group The Klaxons during their gig at the Hare and Hounds pub in Birmingham, England on Monday night (31.03.14).
A source told E! News: "It was the first time the band had played at the Hare and Hounds and Keira stayed for the night and was dancing the entire time, which I'm pretty sure is the sign of someone having a good time.
"I've heard from the small number of people who did manage to meet her on the night that she thoroughly lovely, sweet, polite and very unassuming."
The 'Anna Karenina' star managed to avoid being recognised by most of the band's fans.
The insider said: "She had arrived with the touring party and spent much of the afternoon and evening in the dressing room with the band until they went on stage.
"She then watched from the back of the venue with friends and family of the band and by all accounts remained unnoticed by the audience."
The 'Jack Ryan: Shadow Recruit' beauty and James, 30, got engaged in May 2012, after meeting through mutual pal Alexa Chung, and tied the knot in the south of France last July.

Kim Kardashian donated "loads of toys" to an orphanage in Thailand.
The 'Keeping Up with the Kardashians' star, who is currently enjoying a holiday with her family, including nine-month-old daughter North West, in Phuket, took some time away from the beach to pay a special visit to the Home & Life children's home with her mother Kris Jenner, sister Khloe Kardashian, 29, and half-sisters Kendall, 18, and Kylie, 16, Jenner.
A source told E! News they spent several hours playing with the local children after bringing "loads of toys and soccer balls and board games" to the facility.
Kris' estranged husband Bruce Jenner and his son Brody also joined them at the orphanage.
The insider added: "The kids loved it, they probably didn't have a clue who Kim Kardashian and her family are, but they loved the presents."
The family were spotted painting murals on the walls of the refuge before taking a tour of a local village.
The source said: "The girls were great with the kids. They were very motherly and attentive. Khloe played ball with some of them, too!"
The visit was filmed for the family's reality TV series.
