I made a top ten list several years ago; one thing I noticed about these movies is that every one of them was something I'd seen in a theatre first Not necessarily in order, except the first two:
Little Darlings
Graffiti Bridge (Prince, sort of a more metaphorical retelling of Purple Rain)
Spinal Tap
Babette's Feast
The Grateful Dead Movie
The Godfather
The Last Picture Show
Labyrinth (I get to stare at Jennifer Connely for two hours and the Mrs. thinks we're watching a Muppet movie)
Dog Day Afternoon
American Graffiti
I've been working on another top 10 list, "Ten More" or something. On the list so far:
Pyaar Impossible (Bollywood movie, geek meets beautiful girl)
Bad Santa (even "Bad" is very, very funny; haven't seen "Badder" yet)
The Young Girls of Rochefort (1960s French movie, worth watching just for all the old sports cars - a missed-identity story in the Shakespeare tradition)
Babel (love the way the four separate stories come together)
Mary & Max (claymation Aspies)
The Dam Busters (old WW2 movie that shows pretty rarely because the hero's black lab has a politically incorrect name... they've been working on a remake, but apparently coming up with the right re-name for the dog is holding things up)
The Music Never Stopped (based loosely on the Oliver Sacks story about "The Last Hippie")
Most of these are things I did see on TV/Video first, but we have a much better TV than we used to
