As regarding the utopian/dystopian thread: most of the films (not all) that have been pointed out so far have mainly been science-fiction - ] obviously, because this genre easily lends itself to utopian or dystopian society-models. However, there are several excellent films that present alternate societies without begin science-fiction. The most striking example of this is probably Welles' _The Trial_ from the Franz Kafka novel. It has the themes of an individual against an unknown society (as mentioned by an earlier poster) but is not presented as science fiction, mainly as an alternate society to a large extent modelled on our own (incorporating wedtern ideas of justice and democracy - but distorting them). Hope this helps.
