Starship Troopers is such fun!

and district 9

i know its an obvious choice but come on no one has mentioned the wars?

Star Wars
Starship Troopers (woot woot)
Star Trek (thats right the new one)
Road Warrior
Predator 1 and 2
Terminator (only the original and salvation)

and of course the greatest movie ever made Plan 9 From Outer Space (said with great sarcasm)

i hesitate to suggest any of the sci fi books i've really enjoyed for fear of how they will end up being presented on the big screen. that said, i've often thought Ender's Game or, better yet a really good adaptation of Ender's Game and Ender's Shadow would make a movie that would be really accessible to mainstream audiences and therefore likely popular/ successful.

on the less accessible (so likely less popular) i personally would like to see a film adaptation of either Star Fish or Blindsight by the Canadian author Peter Watts. he comes highly recommended to American sci-fi readers who may not have heard of him.

how about the next millenium?

any millennium will do...:D

Dune

Which millennium, this or that?

PS: Why is 'millennium" so hard to spell? I never get it right the 1st time...

I got a few I like, some of them are also dystopic/apocalyptic however..

::::::::

Equilibrium
The Core
Men in Black I
Alien
Starship Troopers
Stargate
Chronicles of Riddick
Terminator 2
Final Fantasy iii (animated)
Ghosts of Mars
Contact (even if it's a bit long)

yay I got to 10, I can't remember a few more...

Equilibrium
Pitch Black
Aliens
Star Trek 4

I love this genre. I would watch anything remotely sci-fi for unfathomable reasons (at the moment). It might be difficult to name top 10 considering so many out there, but definitely worth a try.
