I think there are a collection of good Sci-Fi films that get mentioned a lot (Blade Runner, ALien, Terminator, the first Matrix film...) Â Here are a few slightly less common films that I liked a lot:
1. Dark City - A sci-fi _film noir_ with great visuals and a great cast.
2. Pitch Black - An australian film, also had an interesting look. Â The sequel ("Chronicles of Riddick") was in many ways a worse film, but fun to watch and had great graphic design.
3. Ultraviolet - The best vampire series ever made, very dark, set in modern-day London.
4. Gattaca - If you like sci-fi that really speculates about the human condition, this is a very thoughtful film with a good cast.
5. Solaris - Tarkovsky's Russian version, not the remake with George Clooney. Â OK, it is very long and slow, but is quite a visual trip, and I thought the ending was amazingly powerful.
6. First Men in the Moon - the British film, kinda goofey, but I really enjoyed it. Â I loved the screenplay concept that the American astronauts find a 19-th century British flag on the Moon. Â Hehe!
7. Starship Troopers - OK, a lot of my friends disagree with me on this. Â But I think Verhoven is very intelligent, and for a leftist Dutch film maker, he did a remarkably faithful job of creating and studying Heinlein's bizarre future political system, with the whole fascist stylism and all.
Movies I wish were made:
1. If Tarkovsky was still alive, I'd love to see him make a film of "Dhalgren" by Samuel Delaney.
2. "War of the Worlds" done as a true-to-the-book period piece by Merchant and Ivory.
Best Bad Science Fiction Film:
Ed Woods movies are TOO bad. Â I'd suggest "Barbarella" as a good candidate.
