And The Festival, by the show’s creators Iain Morris and Damon Beesley, even stars Joe Thomas – Simon in E4’s hit – and Hannah Tointon, who was also in the TV series.
Joe, 34, plays hapless Nick who gets dumped after graduation and has a meltdown.
His mate convinces him to go to a three-day music festival where he drunkenly gets a nipple pierced, is peed on and ends up naked.
The film’s trailer was released yesterday and Inbetweeners fans were delighted.
“Joe and I have a ‘joke’ that everything except his helmet and right testicle have now been exposed.”
One said: “This is basically an unofficial Inbetweeners movie minus Will, Neil and Jay. Looks hilarious, though.”
Another added: “Just watched the trailer and it’s basically Simon at a music festival. I love it.”
The film, due out in August, uses footage from last year’s Leeds Festival where Joe appeared on stage.
Nick Frost and Noel Fielding also star.
Series creator Iain said of the nude scene: “Joe and I have a ‘joke’ that everything except his helmet and right testicle have now been exposed.
