I'm a HUGE Robert Rodriguez fan and it all started with "From Dusk til Dawn" and "Desperado". If you've never seen "From Dusk til Dawn" then you should - it's a classic! How could you go wrong directing George Clooney, Quentin Tarantino, Salma Hayek, Cheech Marin and Harvey Keitel? Not to mention that it set the standard for every Mexican vampire picture ever made!!! :)
Anyway, his newest movie is called "Machete" and is coming out this weekend. I'm hoping to get to see it, but until I do I'll just have to settle for watching the preview:
