"Peaky Blinders" creator Steven Knight says series five is "the best yet" and there will be two more to follow.
The 60-year-old screenwriter says the upcoming season of the BBC drama will have viewers on the "edge of their series", and has revealed there will "almost certainly" be a total of seven seasons.
Speaking to talkSPORT, Knight said: "We just finished shooting a week and a half ago. Series five is done. I can honestly say that it's the best yet. It's really good. It's fantastic and it all fell together beautifully. Great performances and I think audiences are going to be on the edge of their seats."
Cillian Murphy - who plays Tommy Shelby - will be up against it more than ever when the popular BBC drama returns, as the Shelby family try to deal with the 1930s following the financial crash of 1929.
Steven added: "The story of the Peaky Blinders and of the Shelby family gets woven into the political fabric of Britain and Europe as the 1920s end and the 30s begin.
"Tommy Shelby faces the darkest force he has ever faced and his struggle is as relevant today as it was then."
The series will see Tommy approached by a charismatic politician who has a bold vision for Britain, but his response will be a huge decision for both his family and Britain.
Caryn Mandabach, executive producer, added: "Steve's Birmingham saga becomes more fascinating and more relevant with every chapter. This one promises to be the best yet.
"I'm truly grateful to the BBC for their support of such thrilling, immersive and resonant storytelling."
Helen McCrory, Paul Anderson, Sophie Rundle, Finn Cole, Kate Phillips and Natasha O'Keefe will all return to the series, as will Aidan Gillen and Jack Rowan.
