So in the last couple of days, I've come across:

The New York Times' 1,000 Best Movies Ever Made: I counted 289 that I've seen, which is more than anyone else who's linked it. I'm not sure if I should be proud. There were a lot I'm embarrassed not to have seen (M, The Seven Samurai, Blow-Up, etc.), and also some that really didn't seem to belong. (The Tender Trap? And Aladdin? I'll give them Beauty and the Beast, but not Aladdin.)

AFI's 100 greatest movie songs: I think they're running out of things to make lists of. Because of my proclivity for musicals, I've seen 65 of these. (Well, 65 of the songs, there are a couple of the same movies repeated, like Singin' in the Rain and Meet Me in St. Louis.)

I know these lists are silly, but I've always been a sucker for movie lists, even incredibly mainstream ones like the AFI. I love checking off everything I've seen., I love that it reminds me of things I wanted to see. Love it.

I've now seen 71 of the 100 Greatest American Movies list that came out years ago. When it first came out (there was a TV special), I cut the list out of the paper and used it as a checklist for awhile, as part my of my goal to see older movies that didn't suck. (I had realized that a lot of commercial releases are crap, and it was hard to get downtown to the indie theatres. Not so much to get there, I guess, but to convince my friends. Give me a break, I was like, 14. This was major in the development of my interest in film, which is now what I take in school.)
My video store had an AFI wall, with all 100 of the films in order. When I went to the store, I'd just pick something off of the wall. I would see movies just because they were on the list and then I'd get the satisfaction of checking them off. Movies like Annie Hall and Singin' in the Rain, which would become my favourites. I've seen Annie Hall at least once a year since then, and it gets better every time.
(The Entertainment Weekly Top 100 is even better, because it's not limited to American film. It filled my heart with joy by picking Swing Time as the representative Fred and Ginger film. Swing Time, for those not in the know, is the obvious best Fred and Ginger movie ever. Actually, looking at it after having taken a film history class, it's one of the better lists I've seen. It leans a little Hollywood, but it's pretty diverse in terms of directors and movements and countries. I've only seen 66 of them.)
Artsiest list I could find: The Village Voice 100 Best Films of the Twentieth Century, of which I have only seen 33. This might be one to take to the video store, as I'm getting that pretentious.
Also, I have seen 75 of the 100 Greatest Comedies, which came out a year or two after the initial best films list and I also used as a checklist. It led my brother and me to a mutual Marx Brothers obsession, not to mention an undying love of Woody Allen and Charlie Chaplin. (City Lights is number one, but The Great Dictator is one of the funniest and bravest things I've ever seen.)

The thing is, I want to see everything. I wish I had time.
