Another forgotten classic from my youth, ty.Evil Genius for a Better Tomorrow said:That film is "Battle Beyond the Stars" [http://www.imdb.com/title/tt0080421/]
Another version of The 7 Samurai/Magnificent 7 set in space.
also: I dont think anyone has listed One Flew Over the Cukoos yet. Surprising as its frankly one of the greatest films ever made with possibly the only genuinely hate inducing "villain" ever in any movie ive seen. Or Come & See (one of the most disturbing war movies ive seen, certainly the most uncomfortable)
oh & 2 more 2000+ films that must be seen. Amelie (yes everyone has heard of it, but its one of the best films about nothing much ive ever seen) & The Assassination of Richard Nixon (Sean Penn on screen for 2 hours, & you never get bored)
