I saw FotR like 5 times in the theater. The LotR Trilogy in general I've watched a LOT, and that's saying something given how long those movies are.

I've watched Pride & Prejudice (2005) a lot too.

Also, Love Actually. It's not like I love that movie or anything, but it's ALWAYS playing on some channel on the TV. So when there's nothing else to watch, I just watch that. I've seen it at least two dozen times.

Also also, Monster's Inc. I can never get sick of Monster's Ink. I <3 Boo so freakin' much.
