Nice! Quentin Tarantino is one of my favourite directors.
For me, I guess my favourite movie would be Stanley Kubrick's Full Metal Jacket, though that might be because it's fresh in my mind; I've been watching Kubrick movies lately (A Clockwork Orange, 2001: A Space Odyssey, and Full Metal Jacket), so it may have influenced my choice. Nevertheless, Kubrick makes some of the most timeless and influential movies. A true genius.
Godfather. Greatest film of all time.Although maybe godfather part2? either of them.
They form part of my 'film' test. If you haven't seen them, you have no valid point of view to make regarding films! :)
