'The Inbetweeners 2' cast used the movie to indulge their "childish" sides.
Joe Thomas, 30, Simon Bird, 29, James Buckley, 26, and 29-year-old Blake Harrison - who reprise their roles as hapless students Simon, Will, Jay and Neil in the comedy sequel - admitted they revel in their on-screen roles because it gives them an excuse to behave in a puerile way.
Speaking at the world premiere of the movie in London's Leicester Square last night (05.08.14), Blake told BANG Showbiz: "From day one, [the producers] set up an atmosphere whereby if something is funny, it's OK to do.
"I don't think we're individually the characters we play on set, but what I think we do is we regress into the kind of childish, puerile humour that the characters have."
James echoed the sentiment, joking: "You don't have to persuade us a lot to behave like childish idiots! Our excuse is that we're in 'character'."
And 27-year-old Emily Berrington - who plays new character Katie in the new movie - says that although the boys are more mature than their on-screen characters, she still had to endure plenty of gross behaviour.
She said: "They maintain a laddy atmosphere all the time, so there's lots of eating - daring each other to eat disgusting things - a lot farting and doing really terrible thing to try to put each other off.
"But I loved it, it made the whole experience really fun."

Chloe Grace Moretz loves skateboarding with Brooklyn Beckham.
The 17-year-old actress is rumoured to be dating the 15-year-old son of David and Victoria Beckham and she has now spoken about their friendship, saying Brooklyn is a "typical guy".
Asked who is the better skateboarder, she told Company magazine: "I don't know. I mean, he has a pretty small skateboard, and I like more of a long board.
"I think he's a risk taker, like a typical guy, weaving in and out of people. I'm a safety boarder - I don't want to break any bones."
The American teenager has a number of British friends, including Jude Law and Sadie Frost's son Rafferty, 18, and Jonathan Ross and Jane Goldman's daughter Honey, 16.
She added: "I lived in London for sooo long when I was filming 'Hugo' and 'Kick-Ass'.
"I've known Raff, since I was like, 14. And 'Kick-Ass' screenwriter Jane Goldman's daughter, Honey is a good friend of mine, too."
As well as skateboarding, it was recently revealed Chloe and Brooklyn have enjoyed low-key dates at popular spinning gym Soul Cycle in Brentwood, Los Angeles over the summer.
A source said: "They cycle next to each other and are very cute. Always look to be cheering each other on with smiles. They also both seem very competitive, but in a fun way."
Despite being fans of the actress, Brooklyn's parents, David and Victoria Beckham, always supervise his dates with the 'Carrie' star.
The insider said: "Brooklyn is always chaperoned by one of his parents. But both David and Victoria must be okay with Chloe, because they will chat briefly with her and then leave them alone."
The couple started dating three months after being introduced at Paris Fashion Week by mutual friends.

Kieran Hayler "cried like a baby" as Katie Price gave birth.
The former glamour model's on-off stripper husband was present at the birth of his daughter on Monday (04.08.14) and was reportedly in floods of tears when the 36-year-old star underwent an emergency caesarean section after going into labour two weeks early.
A close friend of Katie's told The Sun newspaper: "When the baby was delivered, Kieran started crying like a baby. She feels the birth of his daughter has made him see the light.
"Kieran proved himself to Katie over the last week. He was dressed in scrubs for the operation and she loved it. She joked that the last time he was in clothes like that was for a stripping routine."
Despite recent problems in their marriage following the revelation Kieran had been unfaithful with two of his wife's friends, the couple have grown close in recent weeks and Katie - who gave birth to their 11-month-old son Jett eight weeks early - credits her spouse's support for helping her through her pregnancy.
The insider told the newspaper: "It's only Kieran who has been able to keep her through it all.
"She was so scared about losing the baby. It wasn't a pleasant operation but she was absolutely ecstatic that her little girl was healthy."
Katie -who is also mother to 12-year-old Harvey, nine-year-old son Junior and seven-year-old Princess from previous relationships - has already posted a tribute to Kieran on her Twitter page.
The cute image shows her as-yet-unnamed daughter clutching at her father's finger and the image is captioned: "Daddy's little girl 🙂 (sic)"

Jessica Alba was "p***ed off" about turning 30.
The 33-year-old actress - who has daughters Honor, six, and Haven, two, with husband Cash Warren - found reaching a new decade a lot "harder" than she expected and says it was particularly difficult as being pregnant with her youngest child meant she couldn't celebrate "like a rock star".
She admitted: "I was pretty p***** off. I don't know why it was so hard, it just was.
"I was pregnant [with Haven] first of all, and I really wanted to party like a rock star. I didn't even know I cared about my twenties until I turned 30."
However, the 'Sin City: A Dame To Kill For' actress thinks she has grown more attractive as she has gotten older.
She told Britain's Marie Claire magazine: "I feel like I look better now. I think I came into my own physically in my thirties, even when I'd had kids. I'm actually smaller now because everything kind of hangs off differently.
"But I feel more like a woman, with not such a girl face. I had such chubby cheeks."
The 'Barely Lethal' actress admits she knew as soon as she met Cash, who she married in 2008 after four years of dating, they would be together forever.
She said: "Immediately we felt like really close friends. I don't know if that translates into being swept off your feet, as it wasn't really that; it was more, 'I'm going to this person for the rest of my life because he feels like family already.' And that was even before we started dating."

'Captain America 3' will have "explicitly political" themes.
Directors Joe and Anthony Russo are currently developing ideas for the next movie in the superhero series - which stars Chris Evans in the title role and as his alter ego Steve Rogers - and they are keen for their character not to become a "disillusioned antihero".
Anthony told Yahoo!: "The character was invented for an explicitly political purpose. So it's hard to get away from that nature.
"It's also important that Captain America doesn't become another disillusioned antihero."
Joe added: "His morality is part of his superpower."
The pair were keen not to give too many details away, but did promise the story will "bringing some new elements to the table that will give a twist on [second movie] 'Winter Soldier'."
They also suggested they will explore the troubled relationship between Captain America and his childhood friend-turned-assassin Bucky Barnes (Sebastian Stan).
And the directors advised fans to watch out for several members of their own family making cameo appearances, as is often the case in their work.
Joe laughed: "If you look at the credits of 'Winter Soldier', there's probably 47 Russos in the film."
The movie will pick up some time after the events of 'Captain America: The Winter Soldier'.
It is currently scheduled for release on May 6, 2016.

Matt Richardson rejected a return to the 'Xtra Factor' because bosses wanted him to be more serious.
The 23-year-old comedian - who presented the 'X Factor' spin-off show last year with Caroline Flack - claims he turned down the opportunity because he wasn't ready to give up his comedic nature.
He exclusively told BANG Showbiz: "ITV wanted to change the show to be different this year and even quite early on in the year, I was asked if it was to become more serious, would I still be interested. I wasn't because everything that I do is comedy based.
"It was pretty much sort of them wanting to change it and me not really feeling like there was a place for me anymore."
Sarah-Jane Crawford will now take over the reigns of the ITV show later this year and Matt feels like she's perfectly suited to the role and it's her time to shine.
He explained: "I only met her once ... She's really nice, she's worked really hard - like she's been grafting for 10 years so I think she's due a break like 'Xtra Factor'.
"I don't have any ill feelings. I think she'll be really good and really different, which is what they wanted and I think it's really exciting when shows get new talent in to present. So I think good luck to her."
Matt will next be seen in the Virgin Media Louder Lounge and Virgin Media Our House at the forthcoming V Festival, http://www.vfestival.com, on August 16 and 17, where he will perform.

Danielle Armstrong has admitted her boyfriend James Lock isn't a "typical romantic."
The 'Only Way is Essex' beauty was blown away by her beau's sweet attempts to win her back after she discovered he'd cheated on her earlier this year, but she insists the hunk isn't usually one to show affection.
She said: "James as a boyfriend... he's not your typical romantic, he wouldn't come home with flowers and cook dinner. He's more spontaneous, so I'll mention that I'd like to go to a certain restaurant and he'll just book it without even telling me."
The blonde stunner believes, despite their turbulent romance in the past two series of the show, she and James have become a stronger couple.
She explained: "Obviously we've had our issues in the past, like with a lot of couples we have to go through a lot of drama from time to time but at the moment it's all going well so fingers crossed."
However, Danielle admits one place James' flirty nature is coming in handy is in her shop Dani in Essex because he's managing to charm her female customers into splurging on her gorgeous clothes.
She joked: "James is really good in the shop, especially at charming the ladies! A lot of girls come in and you can see them getting all giggly all round James and if he says, 'Yeah that looks nice,' I'm pretty certain they're going to buy it!"
Danielle Armstrong enjoyed the refreshing great taste of Carlsberg Blackcurrant and Citrus at the Carlsberg Born to be Chilled BBQ in Essex at the weekend.

Mariah Carey has parted ways with her manager.
The 'Hero' hitmaker's affairs are no longer looked after by longtime collaborator and producer Jermaine Dupri - who she first teamed up with in 2005 - and though he will no longer oversee her career, he insists they will continue to work together in other capacities.
Jermaine told Billboard in a statement: "I'm a very hands-on person when it comes to my work.
"I put my all into every project. But when I'm not allowed to do what I do, then I know it's time for me to move on. Mariah and I enjoy working together and will continue to make great music together in the future."
Mariah - whose latest album 'Me. I Am Mariah... The Elusive Chanteuse' has sold just 103,000 copies since its release in May - is now working closely with Kevin Liles, who currently manages Ty Dolla $ign and Trey Songz, though "nothing official" has been signed with his firm KWL Enterprises.
Jermaine recently insisted he wasn't worried about the low sales of Mariah's latest album.
He said: "I actually feel like it's probably one of her best albums she's ever made.
"I'm excited to see where the album ends up. I tell a lot of people, this era of music and this genre, they don't understand records that come out small and sell a lot of records."

Courteney Cox is to get married in Ireland.
The 'Cougar Town' actress has set her heart on tying the knot with Johnny McDaid in Ashford Castle in Lough Corrib, Galway, after falling in love with the building when visiting the Snow Patrol star's family recently.
And the couple will also host a star-studded reception in Malibu afterwards.
A source told The Sun newspaper: "Johnny took Courteney to Ireland to meet his family and they fell in love with Ashford Castle.
"They want to get married there at the end of the year and have a big bash in LA on a Malibu beach afterwards."
The rocker, 38, proposed to the 50-year-old actress - who has 10-year-old daughter Coco with ex-husband David Arquette - in June after just six months of dating.
The pair shared the happy news with their fans shortly afterwards, by each posting on Twitter, "I'm engaged to him!" and "I'm engaged to her!"
Courteney and Johnny were first spotted together in December when they attended the actress' close friend Jennifer Aniston's holiday party in Los Angeles.
However, speculation things were moving very fast began to swirl earlier this year when the couple's mutual friend Ed Sheeran - who introduce them to one another - let slip that they had moved in together.
Meanwhile, Courteney finalised her divorce from her ex-husband David in May last year, but the ex-lovers remain on good terms and share custody of Coco.

Michael Jackson used secret code words for sex, it has been claimed.
Lawyers acting for 36-year-old James Safechuck - who co-starred with the late King of Pop in a Pepsi commercial in the 1980s - have filed court documents asking he be allowed to file a claim against the 'Thriller hitmaker's estate after being molested nearly 100 times over a four-year period until he hit puberty and the documents contain a number of claims against the star.
The documents allege the accuser regularly shared the singer's bed and revealed Michael used code words for sex such as calling semen "duck butter" and describing an erection as "bright light, brick city".
According to TMZ, Safechuck also alleges the singer used secret signals and when they held hands, the 'Beat It' star - who died of acute Propofol intoxication in June 2009 - would scratch the inside of his hand with a finger to show he wanted sex.
Other claims in the documents include Michael performing a secret wedding ceremony complete with a ring and marriage certificate with his alleged victim.
Safechuck says the abuse made him question his own sexuality when he developed a crush on the star's then-backing singer Sheryl Crow - prompting the 'Billie Jean' hitmaker to get jealous and show him a number of unflattering photographs of the 'All I Wanna Do' star.
A lawyer acting for the estate insists the claims should be dismissed as they have been made so late, and because Safechuck has previously insisted nothing happened with the singer.
Howard Weitzman said: "Mr. Safechuck's request to file a late claim against the Jackson Estate so he can recover money from Michael's beneficiary will hopefully be rejected.
"This is a person that made his claim five years after Michael died, more than 20 years after the incidents supposedly happened and has given sworn testimony that Michael never did anything inappropriate to him."
The petition will be heard in court on September 4.

Jake Bugg doesn't watch other artists perform because he thinks it "messes with your head a bit."
The 20-year-old singer claims he's only been to seven gigs in his life because he's worried seeing other people perform will make him doubt his own talent.
Speaking in NME magazine, he said: "I think as a performer it messes with your head a bit. You think, 'What are they doing that I'm not doing?' when you should just get on with what you do."
The 'Lightening Bolt' hitmaker prefers to focus on his own music instead and admits he feels he's let himself down if he doesn't play music one day.
He explained: "I feel disappointed if I don't pick up my guitar in the day. I feel like I've not done anything, I'm not being productive. Relaxing for me is writing songs and having my guitar there."
Meanwhile, Jake has already started work on tracks for his new album, which will be the follow-up to his 2013 'Shangri La' collection, but is determined to stay tight-lipped on the content until nearer the release date.
He said: "I've been trying to keep what I'm doing under wraps at the minute. A producer or someone could stick me on the mics and I'll just make something up on the spot and not share the ideas that I've actually spent a bit of time on because I just want to have a bit more time with it."

Karen Gillan wants to lick Daniel Craig's face.
The 26-year-old actress plays Nebula - the main female villain in 'Guardians of the Galaxy' - and thought it would be a great idea to lick her opponents face in a fight and now Karen wants to become a Bond baddie and do the same to Daniel, who plays the titular spy.
She told Interview magazine: "I just want to lick [Daniel Craig's] face. In the movie I play Nebula, the female villain. She's really sadistic. One time, I had a man in a headlock, and then I just decided that Nebula would lick his face. I feel like she's a face licker."
Karen revealed it was her father who encouraged her to dream of becoming a Bond baddie rather than one of the spy's famous Bond girls.
She said: "My dad used to tell me when I was younger, 'You don't want to be a Bond girl; you want to be a villain. That stuck with me."
Karen shot to fame on 'Doctor Who' playing companion Amy Pond and she credits the sci-fi show for allowing her to hone her craft.
She said: "That was my real acting training. I like the sci-fi fans. It's really nice to be in things that people care about."
