The creator of hit BBC drama Peaky Blinders is hoping to make a spin-off film when the series comes to an end.
Steven Knight, who wrote the Birmingham crime saga will look at a feature length project when the final episode wraps.
Speaking at a festival in honour of the show, Mr Knight discussed his plans for the underworld epic.
He said he would avoid a prequel and wants to stay clear of celebrity cameos, after Liam Gallagher expressed interest in making an appearance.
The writer expects to take his long-form series to the cusp of the Second World War by the final series, then move to the big screen.
He said: "I'm writing series six at the moment. That's almost done.
"Then I'm going to do series seven, then I'm looking at spin-offs, maybe a movie.
"It's up to us. It's up to the people involved."
Mr Knight said he would make a decision on the future film version along with star Cillian Murphy and producer Caryn Mandabac.
The writer has said he would likely steer clear of a prequel, as given the timescale it would end up being a First World War film.
He said: "The problem with prequel is you're limiting yourself as to where it can go.
"You can't kill a character who can show up in the series."
Mr Knight spoke at the Peaky Blinders Legitimate festival in Digbeth, where former Oasis frontman Gallagher made an appearance, being a fan of the show. The writer is reluctant to allow him a role on the show itself.
The show creator added: "He said 'if you do my video, I'll do the festival'.
"In terms of appearances we've always had a lot of incoming interest. What I'm trying to not do is populate the scene with people who are known for other things, because I think it's quite distracting."
The current series of Peaky Blinders sees Murphy's character in a position of political power as a local MP.
