How the Grinch Stole Christmas (2000)

Trivia: When the Grinch takes the table cloth from the table, everything on the table was supposed to fall off. When Jim Carrey yanked out the cloth however, everything stayed in place. Jim immediately walked back to the table and improvised knocking everything off and then knocking the table over.

Trivia: Jim Carrey's makeup took 2 hours to put on and 1 hour to take off, every day for 92 days of filming.

Trivia: Director Ron Howard eventually decided that he had to experience what the cast was going through (since they all had to spend so much time in makeup, especially Jim Carrey) so Howard wore the Grinch makeup one day and directed all day long as the Grinch.

Trivia: The Grinch is imitating Ron Howard in the scene in which he is trying to decide what to wear to receive his Cheermeister award. Watch when he puts on the baseball cap.

Trivia: The widow of the late Dr. Seuss insisted that if the story were made into a movie, no one but Jim Carrey would play the role of the Grinch. Sure enough, she got her wish.

Toolio

Trivia: When Cindy Lou goes up to the Grinch's lair, before she goes inside you can hear him yell "Owiee." This is exactly what Jim Carrey said in "Liar Liar" when he was hitting his head above the urinal (when he beat himself up in the bathroom).

Piemanmoo

Trivia: When watching the giant Christmas tree go up in flames, the Grinch says, "Oh, the Whomanity!" This is possibly paying homage to Herbert Morrison, who famously exclaimed, "Oh, the humanity!" during his witnessing the Hindenburg catastrophe.

Movie Nut

Trivia: Director Ron Howard has a cameo role as one of the startled Whos while the Grinch is ranting in the city square.
