Suggestions from 2011/08/05 for non-obvious SF/Fantasy movies, with many thanks to anyone who answered. Apparently thee isn't much new for me but they were all great suggestions!
- gattaca (suggested twice. Great movie, but also quite known imho)
- dark city (loved it, generally underrated imho)
- primer (mindbending, cheaply made, very geeky)
- La jetée (TBD)
- pandorum (arguably the best "in space" movie to come out recently
- I'm a cyborg, but that's ok (not sci-fi but very enjoyable)
- Videodrome (masterpiece, very old but very famous)
- Aeon Flux (real actors movie: meh; animation: kewl)
