Good question here's 3 of the top of my head
here are some interesting ones

1) THX 1138 (http://www.imdb.com/title/tt0066434/)
George Lucas's first film (funded by Coppola), visually brilliant and has echoes of things to come (including a prototype lightsaber) but far far darker.

2) The Quiet Earth (http://www.imdb.com/title/tt0089869/) these 'last man on earth' films are making a comeback at the moment, this is a classic one from 1985.

3) Outpost (http://www.imdb.com/title/tt0892899/) Only got a limited cinema release this year, very limited budget but the cinematography is awesome and very creepy in places, oh and it contains Nazi Zombies!
