The stars of Peaky Blinders have been keeping fans on tenterhooks about the show’s future for months now.

The BBC recently confirmed that season five was set for release in 2019, and creator Steven Knight has always suggested that he wanted the show’s arc to run between WWI and WWII, suggesting it would be the final instalment.

But then he’s also said that he has the series' end firmly in his mind, and "whether that happens at the end of five is the question" – opening up the possibility of a movie.

Cillian Murphy has echoed the idea of a big screen finish, telling a crowd at Esquire Townhouse: "I think Steve [Knight] has some ideas. You'd have to be careful, but I'd be curious to do it”

He also told Deadline: “Listen, you know Steve has so many ideas, he’s so inventive, I wouldn’t be surprised. For me, I’ve always said as long as the writing stays as good as it is, I’m around.”

But a movie is a big undertaking, and Knight has a couple of other projects on his plate. He’s teaming up with Tom Hardy for a Charles Dickens series, and is also working on a sci-fi project for Apple. He’s even working on a Peaky Blinders musical.

So what’s going on? Are the Peaky Blinders finally finished with their mixed messages? In a word: no.

In a recent interview with Film School Rejects, Murphy suggested he was up for starring in even more series of Peaky Blinders, saying he would be “a fool to walk away from writing this good.”

He said: "I think it will find it’s natural conclusion, and I think we’ve been very, very lucky that the show has, in my opinion, gotten better incrementally, which is very unusual. I feel like we’ve improved each year. You’d be a fool to walk away from writing this good.

“The other thing about it is that I only work for four months a year on this show, and then I have a year off, so I can go and do other things. So it’s kind of a dream gig because you can get to play other characters and explore other ideas and other concepts in between times. I trust in Steve Knight that creatively he will know when to bring it to its natural conclusion.”
