it depends on your age, I don't think you can really change your world view based on movie if you are in 30s or older, but you can be definitely influenced if you are teenager and into 20s
taking this into consideration I would recommend these parts of the movies, you can find them all on YouTube without watching whole movie:
Se7en - final John Doe monologue about innocence of his victims in back seat
Collateral - Vincent monologue on back seat about not doing anything with your life
Fight club - pretty much all movie, very influential, should be mandatory for teenagers
American beauty - less extreme version of fight club for older men that you can rebuild your life even in higher age
the big Lebowski - if you care about your clothing maybe it can help you to watch Lebowski
the beach - encouraged me to travel more, although wanted already before
