Continuity mistake: At the end when the sled full of Christmas stuff is on the mountaintop, it starts sliding off the edge. It's going fast enough that it should be long gone by the time the Grinch reaches it, but when he does it's still right near the top of the mountain.

Continuity mistake: When the Grinch goes into the first house, you can see the Christmas tree in the background and it has a silver star on top. But later when he steals the star, it's gold.

How the Grinch Stole Christmas! (1966)
Continuity mistake: When the Grinch puts the antler on Max's head it has five prongs. But when Max tips forward, one of the prongs disappears as it's hidden behind his body. The Grinch only cuts off four prongs, but when Max goes upright again, the fifth prong is still gone.
