Filming is officially underway for season four of popular British drama Peaky Blinders, and details are slowly spilling in.

The key information to take away from emerging reports is that Oscar-winning actor Adrien Brody has signed up to the cast in an unspecified role.

Creator Steven Knight teased his appearance by saying: “He genuinely was the actor in my head when I wrote the part. I’m sure he will be a formidable presence in the world of the Peaky Blinders.”

Story-wise, the new batch of episodes will begin with Tommy Shelby (Cillian Murphy) receiving a mysterious letter on Christmas Eve which sparks concerns that the Peaky Blinders are in mortal danger. Fleeing his country home, he returns to Birmingham to prepare for oncoming war.
