The writer of Peaky Blinders is hoping a film version will be made when the TV series ends.
Steven Knight, creator of the Birmingham crime saga, is to look at possible spin-offs once the series ends.
The writer said he did not want to pursue a prequel or introduce celebrity cameos after Liam Gallagher said he was interested in appearing.
Knight’s desire is to take the story to the cusp of the Second World War by the final series before a 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.”
He said he would make a decision on the future film version along with star Cillian Murphy and producer Caryn Mandabac.
On embarking on a prequel, he said: “The problem with a 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.”
Knight spoke at the Peaky Blinders Legitimate festival in Digbeth, where former Oasis frontman Gallagher made an appearance.
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.”
