"Colin Farrell Reveals Full Bodysuit for Oz Cobb Role Even Included 'a Penguin Penis' (Exclusive)"

I was basically covered wrist to ankle," the actor tells PEOPLE of his transformation in 'The Penguin.' "The only things that were me were my hands and feet."

Colin Farrell is utterly unrecognizable in his role of Oz Cobb in the new HBO limited series The Penguin.

"I had a bodysuit, so I was basically covered wrist to ankle. Only things that were me were my hands and feet," the actor, 48, tells PEOPLE. "Everything else, including ears, were pieces. Everything was covered."

Farrell's transformation, created by artist Mike Marino, who previously worked with the actor on The Batman in 2022, meant spending about three hours every morning during production in the makeup chair. "If it wasn't for Mike's design, I'm telling you now, if it was just me with a f---ing cigarette and a top hat and a bit of a limp and an umbrella that was a machine gun, we wouldn't have had the HBO show."
