I agree with a lot that were already mentioned, but here's my list:
(in no particular order)
Hogfather
The One (starring Jet Li - like the matrix only with an actual martial artist equiped with superpowers)
Earthsea
Lord of the Rings
Equilibrium
Planet of the Apes (originals were a good idea, remake looked amazing and was pretty good)
Star Trek (The Next Generation ones are my favourites)
The Secret of N.I.M.H. (animated, animals, dark, I had it when I was little kid)
Snow White and the Seven Dwarfs - (its a classic, when it was reissued on video, my dad got one of the first 100 copies so we got a huge free poster)
Men in Black
Alien
Soylent Green
Omega Man
Superman
Total Recall
Jurassic Park
The Wizard of Oz (suprising it was made in 1939, one of the first films I ever saw)
Jason and the Argonauts (all these old movies I saw on tv at my grandads house, or with my dad at home. There's too many to list.)
Sinbad - I saw a few of these
Jumanji
Willy Wonka and the Chocalate Factory
Darby O'Gill and the Little People (Ireland isn't really like this)
Robocop
Terminator
I'm leaving tons out. And the remake of I Am Legend with Will Smith may be good.
Contrary to the above evidence and the fact I've read loads of books, I did actually go outside as a child, it just rained a lot. I'm still squeezing in an education, being "artistic" and playing instruments/listening to music... It just seems more time consuming written down.
