Watch: Cillian Murphy on set of new Netflix Peaky Blinders film in Birmingham

The city's famous heart of the canal network, usually bustling with revellers, was shut down while film crews transformed the area into a gritty wartime film set.

On Monday, October 21, fans saw Cillian reprising his role as Tommy Shelby, with the 48-year-old Irish actor donning the gangster's trademark flatcap. The Oscar winner could also be seen with fake blood trickling down his cheek while wearing what appeared to be a heavily mud-stained jacket and suit.

An onlooker, who could see the scenes being filmed from her office, said: "The whole office kept getting up. It was a distraction the whole day.

“When I was walking into work, I saw all the flash screens and the filming signs. I Googled that they were filming in Birmingham. I saw the actors getting off the coach, but I couldn't make out who they were from where I was.”

It is believed the filming went on for around seven hours, starting at 10am. Stephen Graham was later seen filiming scenes on the canal in Birmingham in the evening.
