Arthouse movies aim to challenge and provoke viewers, giving those brave enough to check them out an experience they're unlikely to have felt before, with certain experimental or unusual elements being contained within. What can be considered "arthouse" is therefore quite broad, with certain movies pushing boundaries more than others. The broadness also allows various films of differing genres to be considered arthouse in nature, and so it follows that one sub-genre is arthouse science fiction.
Sci-fi movies can get pretty strange already, when not also trying to be arthouse, given they depict stories often set in the future and/or revolving around otherworldly creatures/beings/technologies. The following films go one step beyond the bounds of "standard" sci-fi and instead become arthouse sci-fi, also being examples of films that are more or less great, in any event. They're ranked below, starting with the very good and ending with the all-time classics.
