I'm a huge Quentin Tarantino fan. His movies have such a distinct flavor. I'm also a fan of David Fincher (Fight Club, Benjamin Button, Se7en ), Ridley Scott (Gladiator), Steven Spielberg (Saving Private Ryan, Jurassic Park), and Mel Gibson (Braveheart).
I'm ashamed to say, I haven't really seen any Akira Kurosawa movies. Definitely on my list of things to do.
