Hugh Grant wants the Bridget Jones' Diary franchise to be "significantly reinvented" before he signs on for another movie.
Plans are underway for a third film in the series but the actor - who played Daniel Cleaver in the earlier movies - insists he and co-stars Colin Firth and Renee Zellweger have not yet agreed to appear.
He said: "I did like playing Daniel Cleaver, but there is no definite part three. None of the three of us have signed up yet.
"There's been a number of drafts that have had great things in them but haven't quite hit the bullseye.
"But they're working on it again now with yet another writer, as soon as they get to a good point we will do it, I'm sure. It's just that it does have to be significantly reinvented."
Hugh believes the third movie will have to be set some time after the last sequel - 2004's 'Bridget Jones' Diary: The Edge of Reason' - because he and his co-stars look "f***ing ancient".
He added in an interview with Total Film magazine: "I don't think you could pretend that it's a year after the end of the last one because we look f***ing ancient now, all three of us."
