Hmm...here are some of my favorites. (In no particular order)
The Crow (1st one)
The Dark Crystal - an excellent movie! Suprised no one else said it yet.
Shawshank Redemption What Dreams May Come (if you like alternative realities, Ed, you'd probably like this one. If you haven't seen it already)
Time Bandits Heh, this one's hilarious
The 'Burbs Nothing to Lose The 13th Warrior (The acting was so-so, but the story line is
great)
Twister - probably my most watched movie
The Evil Dead, The Evil Dead 2, Army of Darkness - you'd probably not like those movies, though, Gia.
Hackers The Prophecy 1, 2, & 3 Hudson Hawk - probably my 2nd most watched movie
The Princess Bride Ferris Bueller's Day Off The Secret of NIMH Blade Runner A most execellent movie, as Ed already pointed out
Anastasia - Cartoon, but a great one
Nightmare Before Christmas - a classic, in my book
Big Trouble in Little China - if I need a good laugh, I'll always pop this one in.
The Shadow -
Edward Scissorhands Labyrinth (Err, though David Bowie starts getting to me by the end of the movie

)
The Usual Suspects - An awesome movie. Ed, if you haven't seen this one, I highly recommend it.
Insert Just About Every Disney Movie Here - yeah, I admit it, I like Disney movies.
