4. Gary Oldman - Hannibal
This is Gary Oldman we're talking about. The man doesn't do things halfway. So when he signed on to play a role in Hannibal, he was more than game for the intensive makeup sessions. He spent six hours a day in the makeup chair, having his lips prosthetically removed while heavy scarring was applied to his face. Ridley Scott wanted his character's makeup design to be disturbing, but still somehow sympathetic. He wanted people to feel bad for Mason Verger, not to be frightened of him. To that end, he turned down many designs that looked too much like zombies, and opted instead to encourage his artists to be inspired by fetal images, which he thought would allow them to establish an emotional connection between the character and the audience.
