The Batman director Matt Reeves has revealed Colin Farrell's character Penguin was inspired by The Godfather.

Farrell is unrecognisable in the role and while Reeves drew inspiration from many places for the character, it is Fredo Corleone in The Godfather that is particularly similar in how the characters both feel "underestimated."

"There's a touch of John Cazale as Fredo in The Godfather. He's a mid-level mobster guy and he's got a bit of showmanship to him, but you can see that he wants more and that he's been underestimated. He's ready to make his move," Reeves told Empire magazine.

Farrell added, "Fredo's crippled by the insignificance that he lives within, in a family that is full of very strong, very bright, very capable, very violent men. Which is why he commits the act of betrayal that he does, because he's weak, he's kind of broken, and he's in pain.

"There is a kind of fracture at the core of Oz, which fuels his desire and his ambition to rise within this criminal cabal. Where that rise goes...

"I would love to get to explore that in the second film, if that was ever to happen."

The Batman, which will see Robert Pattinson take on the iconic titular role, will be released in March 2022.
