I didn't know this thread even existed, here are a few I recommend:
City of God, a Brazilian crime drama with English subtitles, if you liked the Godfather, I''m sure you will love this, very different but equally impressive. I bow down to the guy who directed this, the cinematography is a work of art.
Godfather trilogy, of course
Burn after reading, a quirky satire about a few stupid Americans, whats not to like about that?...if you like dark shock humor then its a must
Monty Python - the meaning of life, there are 2 types of people, those that "get" Monty Python and those that don't
Monty Python - the life of brian, "
Napoleon Dynamite, frikkin hilarious, nuff' said
Despicable me, best animation of teh year for me
District 9, more than just another alien movie, I found the layers
Borat: The cultural leanings of America...toilet humor and sexist jokes at its best
Other movies that are ok: Blood Diamond, Eastern Promises, Syriana
