2000. dir. Christopher Nolan, starring Guy Pearce, Joe Pantoliano, Carrie-Anne Moss.
Seen it before? Yes.
In my opinion, this is Christopher Nolan's best movie, although I haven't seen Inception yet. By the way, it's #3 on the Top 250 now!? It bumped Godfather Part II. Now I have to see it. Actually, looking over the list, there's a bunch of new movies on there... How To Train Your Dragon? Really, it was that good? Toy Story 3 is #12? Huh.
OK, so, Memento. It's the backwards movie. Well, not really - the black and white scenes go forward, and the color scenes go backwards. Neat device, and it works especially well because the protagonist has no short-term memory. Seeing this for the first time is very disorienting because basically everybody is lying to him and manipulating him, the poor guy.
Position on the list: 29
Hey! It's that guy! Stephen Tobolowsky! I sure as heck-fire remember you! Ned? Ryerson! Bing! Ok, I'm done.
