The cast and crew of the new HBO series talk in great detail about how Colin Farrell transformed on-screen, physically and artistically, into becoming Oswald "Oz" Cobbs.

Colin Farrell figures he has donned the Penguin’s makeup some 90 times – for both the film, “The Batman,” and now, the series, “The Penguin.” And, no, it doesn’t get any easier. He still sits for three hours to get it all applied and, frequently, he’ll need changes or touch-ups just to have the appropriate look.

Colin Farrell looks completely different in "The Penguin," thanks to several hours a day in a makeup chair. Taking it off was "next level" relief.
