Roberto Campanella is a choreographer who has worked on tons of films including It and Beauty and the Beast. He was chosen to play the janitor in Silent Hill, who had his hands and feet tied up. Campanella met the challenge head-on and got creative with the choreography, making The Janitor one of the most unsettling characters of the film.
Emporer Palpatine - Ian McDiarmid
Emporer Palpatine underwent quite the transformation during the Star Wars films he was featured in. Scottish actor Ian McDiarmid took on the role of the powerfully evil character. At first, he didn't have much makeup to deal with. By the end of his Star Wars stint, his character had changed so much that he spent hours in the makeup chair.
