Seth Rogen and Rose Byrne are "stupid people" on a "dumb mission" in 'Bad Neighbours'.
The 23-year-old comedian and his 'Bad Neighbours' co-star play a young couple with a newborn baby whose home lives are turned upside down when when a college fraternity moves into the house next door.
The pair try to get revenge on the students for their blazing house parties which keep them up all night and the film's producer Evan Goldberg insists Rogen's character is different from the parts he usually plays.
He told the Hollywood Reporter: "Normally in Seth's movies, he's combative. In this, though, Rose Byrne and him are a team. They are both stupid people in a dumb mission that they shouldn't be doing."
Goldberg's co-producer James Weaver agrees that the 'Superbad' actor takes on a more mature role while 'That Awkward Moment' star Zac Efron is the childish one.
He said: "[Rogen] is an adult in the movie, which people are talking about. Zac is the kid, and Seth is doing adult things."
Rogen - who is married to actress Lauren Miller - admits that he had difficulties looking after his screen baby as he's not good with children.
He explained: "Babies are not fans of me either, and we made sure they were fine by me before we casted. These babies were good, but most I'm not cool with."

McBusted don't think other supergroups would be able to fake the chemistry they have.
The group, made up of Mcfly's Tom Fletcher, Danny Jones, Dougie Poynter and Harry Judd and Busted members James Bourne and Matt Willis, have heard other boy bands are planning to follow suit and join forces but don't think they'll be as successful as McBusted.
Singer Tom told the Daily Star newspaper: "I heard Boyzone and Westlife are rumoured to be doing something similar to us.
"The thing is, I'm not sure if it would work as well for other bands.
"Good luck to anyone wanting to form a supergroup, but it probably won't be as easy and natural as it was for us.
"McFly and Busted go way back. I was in Busted for a while before McFly, plus Harry and Charlie [Simpson, from Busted] went to school together and I went to school with Matt.
"James has written most of McFly's hits. So the lines between the two bands have always been blurred. For us to merge seemed the natural thing to do."
McBusted have kicked off their 34-date arena tour but Tom, 28, admits it hasn't been very rock and roll behind the scenes.
He said: "I think we've all been too busy crapping our pants about the show to be honest.
"But there'll be plenty of time for backstage antics and pranking from now on.
"We're such good mates and touring together is so fun."
The band will play their biggest gig so far on July 6 when they headline Barclaycard British Summer Time at London's Hyde Park.
They will be joined by Backstreet Boys, The Vamps, Scouting For Girls and Lawson.

Mariah Carey's children will feature on her next album.
The '#Beautiful' singer - who has two-year-old twins Monroe and Morocco with husband Nick Cannon - has revealed her children sang on her track 'Supernatural', which will be included on the upcoming record.
Mariah told Wonderland magazine: "There's a song on the record called 'Supernatural' that I haven't talked to the media about before - it features Roc and Roe.
"Especially Monroe - that's her song. She opens the song, actually. It was something along the lines of 'Goo goo goooo.'"
Mariah has become famed for her eight octave vocal range, and it now looks as though her daughter Morocco is following in her footsteps, as she revealed the tot has a strong voice.
The 44-year-old pop star added: "For a two and a half year old, she was a steady vibrato."
Meanwhile, Mariah's record label have denied reports she is planning to put a surprise album online after Beyonce's released her album digitally without any marketing or advertising in December last year.
Def Jam's Executive Vice President, Darrale Jones, said: "Mariah will announce the date and title in advance of the on-sale date."
The label executive also confirmed the album is due for release next month.

Britain's Prince Harry's split from Cressida Bonas is "amicable".
The 29-year-old royal and the 25-year-old socialite have reportedly separated after two years of dating, and despite claims the prince called time on the romance because he found Cressida too "needy", insiders insist the decision was mutual.
A source told MailOnline: "Unfortunately it is true, they have split up. But this suggestion that the prince supposedly 'dumped' Cressida because she was 'too needy' is so wide of the mark.
"It is a very amicable split and they are still very much the best of friends. They have just decided to go their separate ways."
Several friends believe the pair - who recently sparked speculation they were set to get engaged after making their first public appearances together - will eventually get back together once Cressida, who recently graduated from dance school and is currently working for a marketing company, decides what she wants to do next.
Another source said: "Cressie is only 25 and pretty young for her age at that. Prince Harry will be 30 this year and is at a different stage in his life. He is incredibly fond of Cressie and understands that she wants to do something with her life and with her career before she considers settling down.
"It wouldn't surprise me in the slightest if they got back together in a few months time."

Bruno Tonioli thinks it will be "tough" to beat 'The X Factor' in the ratings this year.
The 'Strictly Come Dancing' judge thinks the rival show will see a ratings boost this year with Simon Cowell and Cheryl Cole returning to the judging panel, but still thinks the BBC One dance contest will triumph when they go head-to-head for viewers.
Speaking at BritWeek in Los Angeles, he said: "Cheryl and Simon have a unique chemistry on screen that the viewers really like, so they will be a strong show this year.
"It will be tough. But we still want to be best.
"Our team is working around the clock 24/7 to make our show the best.
"They work like crazy to make sure we are ready and that our contestants are ready.
"I think that is one of the reasons we are number one.
"We will continue doing what we do and I hope we win again."
Bruno - who is joined on the 'Strictly' panel by Craig Revel Horwood, Len Goodman and Darcey Bussell - and Simon are good friends but he admits they are very "competitive" over their rival shows.
He said: "Simon is a good friend, but when it comes to the shows we are competitive.
"We are friendly rivals."
And the 58-year-old Italian claimed his pal has even confided in him with who is joining himself, Cheryl and Louis Walsh on the judging panel.
Bruno claimed: "I know who it is, but I cannot say."
But asked if he would ever leave 'Strictly' for the rival show, he added: "No, I love 'Strictly'."

Robbie Williams is hoping for a son.
The 'Candy' hitmaker and wife Ayda Field are expecting their second child together and he would love to have a little brother for their daughter Theodora 'Teddy' Rose, 20 months, though he insists another girl would be "cool".
He said: "We don't know if it's a boy or a girl but we're going to find out.
"If we have a girl, it'll be totally cool but I would quite like a little boy.
"Last time I said that as long as it was healthy, I didn't mind. Then we found out we were having a girl and it was a really strange emotion. I was like, 'What am I going to do with a girl?' "
The couple intend to find out the sex of the baby in the same way the planned to with their first child, but Robbie admits they will need to be more organised this time around.
He explained to The Sun newspaper: "With Teddy, the doctor put the sex into an envelope. We went to dinner and the plan was to open it at the end of dinner... but she forgot the envelope.
"I think we're going to do the same thing -- but remember the envelope this time. I don't think we can do it any other way."
The 40-year-old star kicked off a new tour this week and, with Ayda, Teddy, his dad Pete Conway and his mother-in-law joining him on the road, he admits it is very different to previous jaunts and his wife and daughter's needs come first.
He said: "It's a very loving, very safe environment. Our biggest concern these days is that we don't travel through Teddy's nap time.
"We don't get time to worry about us or the show.
"We've got it all going on backstage. Ayda is the happiest and centred and then she's completely not for a few hours, the whole rollercoaster of emotions... "

Gwen Stefani has officially joined 'The Voice USA'.
The 44-year-old singer will take a seat on the panel for the seventh series of the show, Christina Aguilera - who is currently on hiatus from the programme as she is pregnant with her second child - confirmed on twitter.
Christina wrote: "So excited to have you join #TheVoice squad @GwenStefani! Welcome to our crazy fam! Kisses- xoxo #blondesdoitbest (sic)"
Gwen later confirmed the news herself, posting a photo of her hand in the show's signature V shape while clutching a microphone on her Instagram page.
She added the caption: " "It's true! @nbcthevoice.(sic)".
However, Gwen's appointment will be shortlived, as NBC's official announcement about the new series also confirmed Christina will return to the show in season eight.
Original coaches Adam Levine and Blake Shelton - who are working alongside Usher and Shakira on the current season - will also return, while 'Happy' hitmaker Pharrell Williams will take the fourth seat on the panel.
Both Gwen and Pharrell will perform on the show's live telecast next Monday (05.05.15).
Host Carson Daly recently said he thought Gwen - who has sons Kingston, seven, Zuma, five, and Apollo, two months, with husband Gavin Rossdale - would be a good addition to the show.
He said: "She's friends with the other coaches but has a strong opinion, which is also important.
"They can't all just be too lovey out there. So I think she'd be a solid choice."

Jon Voight can't wait for his granddaughter Vivienne Jolie-Pitt's film debut.
The proud grandfather is looking forward to seeing daughter Angelina Jolie's little girl following in the family footsteps on the big screen as she appears alongside her famous mother in new Disney movie 'Maleficent'.
Jon gushed to People.com: "I'm excited to see how Vivienne did. I'll be there. I'm so excited."
Vivienne, five, plays the young Princess Aurora in the 'Sleeping Beauty' reimagining and it seems the little girl had plenty of support on set from her famous parents, Angelina, 38, and Brad Pitt, 50.
Jon said: "Apparently when they were doing it, the funny thing was, Angie and Brad were off-camera trying to get her to respond. You know, telling her, 'You're happy and you're running through the field.' And they followed her with the camera. That's what I heard. That's what I read. I can imagine that!"
And regardless of how Vivienne fares on the big screen, the 78-year-old actor - who is also grandfather to Angelina's children Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and Vivienne's twin Knox - says he will be "proud" of her.
He added: "It's just like any grandchild. You're going to be proud of her no matter what she did."

Gwyneth Paltrow won't be attending the Met Ball.
The 'Iron Man' actress has declined to accept Anna Wintour's invitation to the prestigious event at the Metropolitan Museum of Art in the wake of her split from her husband Chris Martin after 10 years of marriage.
Her representative told Threads magazine: "Gwyneth will not be in New York and is unable to attend the ball."
This comes after Gwyneth slammed the high-profile gala, which is being held on May 5, in a radio interview last year, during which she also professed to being "drunk".
She declared: "It sucked. You always think, 'Oh my god, it's gonna be so glamorous and amazing and you're going to see all these people,' and then you get there and it's so hot and it's so crowded and everyone's pushing you."
Sources have insisted the A-list actress was definitely on the limited guest list for this year's extra exclusive event, despite her comments.
A VOGUE spokesperson told Threads the magazine "is always happy to have Gwyneth attend the Met Gala."
Gwyneth, who has children Apple, nine, and Moses, eight, with Coldplay frontman Chris, was recently forced to dismiss claims her lifestyle website Goop.com was $1.2 million in debt, promising some "exciting" changes in future.

The 'Star Wars: Episode VII' cast has been officially announced.
Harrison Ford, Carrie Fisher, Mark Hamill, Anthony Daniels, Peter Mayhew and Kenny Baker will all return to the franchise, while as previously rumoured, John Boyega, Adam Driver and Andy Serkis will also have roles in the movie.
In addition, 'Mr. Selfridge' actress Daisy Ridley, 'Inside Llewyn Davis' actor Oscar Isaac - who was first linked with the project yesterday (29.04.14) - 'Harry Potter and the Deathly Hallows' star Domhnall Gleeson and Swedish actor Max von Sydow have also been announced as appearing.
Director J.J. Abrams said: "We are so excited to finally share the cast of 'Star Wars: Episode VII'.
"It is both thrilling and surreal to watch the beloved original cast and these brilliant new performers come together to bring this world to life, once again. We start shooting in a couple of weeks, and everyone is doing their best to make the fans proud."
The movie, which has a screenplay written by the director and Lawrence Kasban, opens worldwide on December 18, 2015.

Billie Faiers collapsed and woke up to find her baby wasn't moving.
'The Only Way Is Essex' star is pregnant with her first child with fiancé Greg Shepherd and after collapsing at her pal's Harry Derbridge's birthday bash, she woke up the next morning to find the baby wasn't kicking like she routinely does around 6am.
Billie explained to Now magazine: "I felt a shudder coming over my whole body. It was like my body was shutting down - I had no control over any part of me.
"My ears were ringing. My head hit the table and I couldn't move. Then everything went down.
"[It lasted for] about five minutes. Then I could see, but I couldn't move. I was lifeless, my bones ached, but in my belly I could feel loads of rapid movement. I thought, 'Oh my god, my baby is in distress.' "
Although she didn't go to hospital, Billie went to bed and the next morning panicked when she realised she couldn't feel anything.
She said: "When you're pregnant you know your baby's routine of movement and every morning she'd wake me up. But I woke up at 6am and couldn't feel anything. I lay there for five minutes ... nothing. That's when I panicked, 'What if there's something wrong with the baby.'
"I was hysterical. I rang Sam and screamed, 'I cant feel the baby move!' "
Billie's mother, sister Sam and her boyfriend Joey Essex came over to see her and after about 40 minutes, much to Billie's relief, the baby kicked.
She added: "After about 40 minutes [she kicked]. They made me have tea and biscuits to stimulate something. My aunt had her hand on my belly and suddenly we felt a kick. It was the biggest relief ever. Only then did I ring Greg and tell him what had happened."

Zoe Lucker insists it will be "sad" to see 'Waterloo Road' end.
The 40-year-old actress played crime family head Carol Barry in the BBC One school set drama up until last November.
Although she had already left the series when it was announced it was being cancelled this month, Zoe's first thought was for her castmates who had been on the programme for a long time.
She told BANG Showbiz: "For me, I'd left in November anyway so I knew I wasn't going back, but for my friends who were staying and had been in the series for a long time, my first thoughts were, 'Oh, I hope they're OK about it,' because they've done that amount of time in the show.
"They're still filming another series of it, so they'll be 20 more episodes and then it will come to an end. It will be sad to see a lot of the characters go."
However, Zoe wasn't surprised by the news 'Waterloo Road' - which stars Laurie Brett, Angus Deayton and Melanie Hill - was being axed because it first appeared on screens in 2006 and will have reached 10 series when it's taken off air in 2015.
She added: "I wasn't really shocked by the news, because it's been going for 10 series now ... Everything has to end at some point. With most of the shows that I've done I've tended to go in for a couple of years and then come out. Usually, shows often run for about five or six seasons and then people decide that maybe it's time to go in a different direction."
Zoe has recently started working with FindAnyFilm.com to support their campaign to inform parents about how they and their family can enjoy film and TV safely and legally online and avoid damaging malware and bogus features which will corrupt their home computers.
The screen star wanted to get involved to protect her five-year-old daughter Lilly - her child with her husband James Herbert - from being exposed to potentially damaging internet content.
She said: "I got approached as a mum really, I'm a massive technophobe and I do get very concerned about the internet and the sites that our children are visiting. I've got a five-year-old daughter who is really into film and she loves watching it on my husband Jim's laptop ... Obviously, at this age I can monitor her and supervise her all the time but as she's getting older I know she's going to want to visit these sites and we don't always know whether they're rogue or not. For me I really wanted to push the Findanyfilm.com site so that parents know that there's somewhere where their children can go to download legal films."
