Cillian Murphy issues warning to people watching Peaky Blinders movie in cinemas

Cillian Murphy has issued a stern warning to everyone heading out to watch Peaky Blinders: The Immortal Man in the cinema.

Murphy reprises his role as the iconic Tommy Shelby for Stephen Knight's big screen adaptation of his hugely popular series, which introduces us to Saltburn actor Barry Keoghan as the patriarch's eldest son, Duke Shelby.

The events of the film take place during 1940, with Tommy living life as a recluse and reeling the losses he's faced over the years.

Meanwhile Birmingham, an industrial centre for WW2 Britain, is facing heavy bombardment while the Peaky Blinders are caught up in a scheme by the Nazi's to bankrupt the country by flooding it with counterfeit money, based off of the real life Operation Bernhard.

Stephen Graham, Sophie Rundle and Packy Lee also reprise their roles as Hayden Stagg, Ada Shelby and Johnny Dogs while Tim Roth and Rebecca Ferguson also join the cast.

The Immortal Man has a limited theatrical release before streaming on Netflix from 20 March, meaning fans have a two week opportunity to see Tommy Shelby on the big screen.

And 49-year-old Murphy has a stern warning for anyone who heads to the cinema in the next couple of weeks – don't spoil it.

A clip recorded by a fan which plays either at the beginning or end of the film sees Murphy telling viewers: "Spoilers are terrible, keep it to yourself. By order of the Peaky Blinders."

Which is pretty solid advice.

Listen to the clip below:

The message certainly tickled fans, with one person writing: "yesss!!! very cillian coded and gave everyone a great laugh before this wild ride," while a second added: "Saw it yesterday. Loved that he did that."

And with Murphy's words in mind, the next part of this story will contain spoilers for Peaky Blinders: The Immortal Man, so leave now if you don't want to be spoiled.

What happens to the Shelby family in Peaky Blinders: The Immortal Man?

When Knight previously confirmed that future spin offs would move away from the original Shelby siblings and onto the 'new generation' of Peaky Blinders fans were understandably worried.

And it turns out they had every right to be, as The Immortal Man sees us say a heartbreaking goodbye to Tommy Shelby - aka, the man who inspired a million haircuts - and his sister Ada, who both die in the film.

It's also confirmed that eldest sibling Arthur Shelby is no longer with us, with the The Immortal Man explaining that he died off screen before the events of the film kicked off and is a key part of the reason Tommy becomes such a recluse.

Paul Anderson has since opened up about his reaction to his character's fate, telling LADbible that he was given a heads up about Arthur's 'sad' ending before the premiere.

"I think it’s great," Anderson said of Arthur's death. "I mean, it’s such a powerful thing to do. It’s something you don’t see on TV."
