The Inbetweeners star Joe Thomas has admitted to feeling nervous about the prospect of making a film about the four foul-mouthed teenagers.
But the actor, who plays good-looking Simon, said the new challenge stops him feeling too sad that the TV show has come to an end.
On the red carpet at the Galaxy National Book Awards, he said: "We are making this film so it's not over. In a way that's going to be a huge challenge so I feel quite trepidatious if anything. I feel a bit sad but I'm gearing up for this new thing."
The boys have done some filming already in Malia, Crete, but are preparing to start shooting the movie in earnest from February.
Although they will be in a different setting, Joe said the friends will essentially be the same characters viewers know and love.
"They're abroad so they have been set loose and will trying to spread their wings and sort of assert their freedom and adulthood and the fact they're moving on from school. But I think they'll still be the same young boys."
Co-star Emily Head, who plays Simon's object of affection Carli, has also been promised a role in the movie.
"I've been told I'm in it but I haven't read a script yet," she said.
Joe added that Simon and Carli's will-they-won't they relationship would probably "work its way to some sort of conclusion" in the film.
"They're growing up and leaving school. Those teenage relationships can't go on for ever," he added.
