During an interview with Variety, Farrell briefly discussed the process of transforming into the Penguin's look in "Batman." According to the actor, his Penguin makeup and hair took four hours until eventually it was cut down to two.
Farrell goes on to say that his motivation for accepting a supporting role in the film was the director Matt Reeves.
"Matt Reeves is a wonderful filmmaker, so I was just grateful to be allowed anywhere near it," Farrell said.
About The Batman, the actor said:
"Hopefully people are entertained by it and moved by it. "It's a very unique take on a story that's often been told."
Farrell also discussed his work in "After Yang," the story of a father and daughter who try to save their robot babysitter after he malfunctions.
Farrell was reportedly so unrecognizable that people on the set of Batman didn't recognize him. The actor won't have a big role in "Batman," but Warner Bros. and DC Films want his Penguin to be a part of future projects.
"Batman" also stars Robert Pattinson as Batman, Paul Dano as Riddler, a serial killer tracked by Batman, and Zoe Kravitz as Catwoman.
In the film, written and directed by Matt Reeves, Batman is at the start of his career as Gotham City's protector. Inspired by comic books like Batman: Year One and The Long Halloween, Reeves' Batman will showcase several iconic villains like Riddler, Catwoman, and the Penguin.
"Batman" comes to theaters on March 4, 2022.
