The film was shot between September 1999 and January 2000. Geisel visited the set in October 1999. Much of the Whoville set was constructed on the backlot of Universal Studios behind the Bates Motel set from "Psycho". Rick Baker was hired to design and create the film's prosthetic makeup for Carrey and the rest of the cast. It took a number of tests, and ultimately Carrey admiring a photo of Baker in his first test makeup, for the decision to use Baker's original makeup design. The Grinch suit was covered in yak hair, dyed green and sewed onto a spandex suit. The application of the makeup took up to 8 and a half hours, after which a frustrated Carrey kicked a hole in the wall of his trailer. Carrey's makeup artist Kazu Hiro recounted, "On set, was really mean to everybody and at the beginning of the production they couldn't finish. After two weeks we only could finish three days' worth of shooting schedule, because suddenly he would just disappear and when he came back, everything was ripped apart. We couldn't shoot anything." Kazu Hiro left production until Baker and Howard had a discussion with Carrey on how important Kazu Hiro was to the production. Carrey agreed to keep his anger in check and Kazu Hiro returned to his role. Meanwhile, Josh Ryan Evans, who played the 8-year old Grinch, wore the same style of makeup and bodysuit that Carrey wore. In total, Carrey spent 92 days in the Grinch makeup and became adept at remaining calm while sitting in the make-up chair. Most of the appliances the actors wore were noses that connected to an upper lip along with a few dentures, ears and wigs.
