The Matrix - Plato's parable of prisoners in the cave
2001: A Space Odessey - kubrick's best
Stars Wars
Blade Runner
Metropolis -ahead of it's time in visual effects
T-2
Hitchhikers Guide to the Galaxy - comedy best Galaxy Quest too
Starship Troopers - cheezy but entertaining
Star Trek: First Contact & Nemesis
Planet of the Apes - You blew it all to hell... lol
Omega Man - Cult classic
The Day The Earth Stood Still
War of the Worlds - original not Tom Cruise crap
A.I. - personal fav

of course! i forgot about hitchhikers guide!

The Cube
The Matrix

They where said before but i prefer, old fasioned korean/japanese horror movies the most so sci fi isnt something i would go out of my way to watch. or even remember unless its really good.

hitchhikers was cool, 2001 a classic. Cant think of much decent sci fi out this year....

In order:

Event Horizon (Nothing I've seen comes close)
The Cube (I wanna go to the blue room!)
Terminator 2 (3 was a let down, 1 was ok, not great)
Barbwire (I like the idea of an apocoliptic setting...dunno why, just do)
X-Files Movie (I just like the X-Files)

PS: "Hitchhikers Guide to the Galaxy" was good as a film, but was a HUGE letdown if you've read the books. They should remake the series as it was written tho. Using the marvin from the film

Series' would be:

X-Files (got first 9 season in nice big boxsets and film, all special editions)
Farscape (got all four seasons, but my mate is copying Peacekeeper Wars 4 me)
Star Trek. Vayager (It's the only one I like, my mates obsessed with DS-9 tho)

Can't think of anymore sci-fi series' I follow really. thats about all the geekiness in me lol

Bladerunner for me....... huge Tirger Hauer fan years back.

Then my little green friend and starwarsit ..must be... it is !!

The Matrix 1,2,3

reloaded is the better of the 3 but great films. after you have watched them 15 times over to understand what is going on

Without a doubt, STAR WARS 1 - 6. Terminator 1 & 2 were good but let down by the 3rd installment. Spaceballs is another must to see if you never have before. How about Bicentennial Man (Robin Williams) and Men In Black? Do they both count? Regardless, they are great films in my opinion

Not ever one vote for BATTLESTAR GAllACTIA
Men in Black was funny

in no particular order

Cube - Cube squared and Cube zero were crap though
Starship Troopers - If your pissed, book's better
Akira - Rogue telekenetis mutants destroy tokyo
12 Monkies - Brad, Bruce and Terry gilliam
Blade Runner (directors cut) - you know they trying to do a directors directors cut

even if they don't top yours you have to watch them anyway

I guess alot of the females out there don't watch Sci Fi. Here's my picks

1] The Road Warrior

2] The Blood of Heroes [if you can find it, RENT IT!!!]

3] All of the "Cube" movies [I pray for #4]

4] Battle Royale [from Japan, word on the street is there's gonna be a North American re-make]

5] Aliens - in this order - #2, #4, #1, #3

Star Wars, without doubt lol. I can still picture in my head the whole day, when i sure it and that was way back in 77. Can't even remember the last film i saw nowdays lol

Blade Runner. Undoubtedly.

Also got to agree with AI, and the 'Cube' movies.

Brave New World was great. Although I'm probably biased because I loved the book.

Also not strictly sci-fi... but Battle Royale is a fantastic film. Pity the sequel was dross.
