Top 10 Sci-Fi Movies?

[violet lightning]

Judging from what I have read, it seems alot of people here like sci-fi movies, myself included.
So, what are your top ten all-time sci-fi movies? (I know, if you really like sci-fi, its hard to pick just 10)

Heres my first try: (in no particular order)

1. Alien
2. Blade Runner
3. War of the Worlds (remake)
4. The Quiet Earth
5. 12 Monkees
6. City of Lost Children
7. Star Wars
8. A.I
9. Close Encounters of the Third Kind
10. The Hitchhiker's Guide to the Galaxy

(honorable mentions: "Dark City", "Fifth Element", and the latest "Star Trek" which I thought was well done)
