How the Grinch Stole Christmas (2000)

Continuity: After the Grinch stole all of the presents, Officer Wholihan gets into his police car and drags the mayor's bed from out of his house. When the bed smashes through the window it breaks the top off the middle post of the bed. Then when it comes back to the shot of the bed it's been fixed.

Continuity: After the Grinch unscrews the light bulb in the town Christmas tree, all the lights in the town go dark and the Grinch starts to take off in his sled-thing. When they show a close up of him, the lights are on. Then a few seconds later, the lights are off again.

Revealing: When the mayor has his head shaved by the Grinch, Clint Howard grabs the clippers and shaves his own head down the middle. His hair is yanked off of his head before the he even moves his hand. Even better in slow motion.

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.

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).

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.
