James Buckley says "there's not enough money in the world" to convince him to play Jay Cartwright again.
'The Inbetweeners' star - who played the sex-obsessed character in three series of the E4 sitcom and two feature films - has admitted the show is still so "universally loved" and he wouldn't want to risk ruining it with a comeback.
Appearing on 'The Chris Moyles Show' on Radio X, James was asked if he would be interested in a return one day, but he insisted he wouldn't even read a script.
He explained: "I don't want to go near it anymore... Not because I don't think I would have an amazing time doing it, because I know I would.
"I love the boys, I love the writers. Doing 'The Inbetweeners' was the best job in the world.
"All we did was muck around all day long and they filmed us doing it, and at the end of the day, we might have had an episode, or a TV, you know, or a film or something. It was the best job in the world.
"But it might - you know, as I'm getting older - it's looking like it might be the only thing that I do professionally that is universally loved. There's not enough money in the world for me to spoil that."
However, James - who appeared alongside Simon Bird, Joe Thomas and Blake Harrison in the show and movies - still gives fans a taste of Jay on Cameo as he regularly fulfills requests from people wanting videos in the characer's outrageous style.
He said: "People still really like that character... You know, you can either go two ways with that.
"You can sit there and sort of go, 'Oh, that's not me, I'd like to move on and do other things now,' or you can sit there and go, 'You know, I quite liked doing it and I thought it was fun at the time, and people seem to still enjoy it'.
"And yeah, listen, as an actor, it's difficult professionally for me to move away from that character.
"But you can't have it all, can you? You can't be in a big hit sitcom, and then moan about it after!"
