As this is a scifi and fantasy board, this includes only the materials that can be categorised under these sections. Think what you'd find in a comic book store or that section of a video or book store.
This includes films from Star Wars to A Clockwork Orange, and from Close Encounters of the Third Kind to Lord of the Rings.
This excludes strictly action/thriller movies without a scifi twist (ie. Die Hard, Lucky number Slevin, Se7en, etc.).
If its a hollywood movie, please ensure it is in (or at least includes) original English. English movies dubbed into German/etc. shouldn't be psoted. If its English/Whatever dual audio then that's okay (although on a personal note i'd beg that you reconsider releasing like that and dump the dub [release it seperately if you have to] )
