I love movies so much that I cannot make any sort of list, I can only mention some of the ones that had not been mentioned here (some for obvious reasons as they are from Argentina) that I like.

- Battleship Potemkin
- 2001: A Space Odyssey (well indirectly mentioned by Charles)
- Nine Queens
- Confidence
- War of the Arrows
- The Wages of Fear
- The Man Who Would Be King
- Plata Dulce
- Old Boy
- The Matrix

Oh boy, I can go all day, and I didn't even start!
