He’s green, he’s mean, and he’s been stealing Christmas since 1957. Dr. Seuss’s classic book How the Grinch Stole Christmas has sold millions of copies worldwide and inspired movies, TV specials, video games, and more.

Now you can catch the story on the big screen in a computer-animated movie. It follows the story of the Grinch, who is tired of watching his neighbors in Whoville celebrate Christmas. So, poorly disguised as Santa Claus, the Grinch and his trusty dog, Max, sneak into Whoville to steal the town’s presents and decorations. But when he realizes he can’t steal their Christmas spirit, he has a (literal) change of heart.
