The Creeper - Jonathan Breck
In the film Jeepers Creepers, the main antagonist is The Creeper himself. Jonathan Breck had to undergo some pretty intense makeup to fully get into character. It would take anywhere from three to five hours just to suit up and be ready to film for the day.
Ari - Helena Bonham Carter
It's not a Tim Burton film is Helena Bonham Carter isn't in it, even though she's extremely unrecognizable. Carter had to sit for hours while she was suited up, and described the costume as "unbearably hot" and "very unpleasant." Much of the Ari suit was made of rubber, including her hands and ears.
