Colin Farrell, known for his role as 'The Penguin' in the HBO series, found immense relief in removing the character's extensive makeup each night.
The transformation process, which involved prosthetics and hours of application, gave him a unique perspective on his own appearance.
Farrell compared the experience to a cat looking in a mirror, acknowledging that he never fully lost himself while wearing the makeup.
He credited the show's writers for providing him with compelling material to fill the blank slate created by his altered appearance.
