In How The Grinch Stole Christmas, Jim Carrey had to complete torture-endurance training from the CIA to help him get through the daily 8.5 hours of Grinch makeup.
Carrey said that the makeup took so long to put on that it felt like he was "being buried alive every single day." After the first day of shooting, he went back to his trailer, angrily kicked his leg through the wall, and told director Ron Howard he didn't want to do the movie anymore.
