I saw the movie yesterday and prior to it I really didn’t know anything about it other than it was based on a novel, which in turn is about a man from Earth ending up on Mars and having great adventures, and that it includes the green martians, which have obviously been adapted into AD&D as three-kreen. Actually, the whole thing looks like it was the inspiration for 80% of Dark Sun.
Oppinions about the movie seem to be quite mixed. I’ve heard and read that it’s both a quite good movie and a rather crappy one. But Dark Sun is awesome and so are Conan and Cthulhu, which originated in the same cultural environment and period. So I went to watch it anyway, but not expecting much. If all I would get would have been some pretty visuals that provide me with a few inspirations for my homebrew setting, it wouldn’t have been a complete waste of time.
