How the Grinch Stole Christmas! (1966)

"You're a mean one, Mr. Grinch"

Bitter and hateful, the Grinch is irritated at the thought of a nearby village having a happy time celebrating Christmas. Disguised as Santa Claus, with his dog made to look like a reindeer, he decides to raid the village to steal all the Christmas things.
