Tarantino hasn't done that much stuff, but off the top of my head, here's the other movies he's been involved with:
True Romance- He wrote and Tony Scott directed. Worth watching.
From Dusk 'til Dawn- Collaborative effort with Robert Rodriguez (director of Sin City and the Spy Kids series.) You'll either love this flick or hate it.
Natural Born Killers- Based on a story idea by Tarantino, some of the dialogue is still his, but you have to put up with Oliver Stone's masturbatory directorial style.
Four Rooms- I haven't seen all of this, but from what I'm told, the only stories worth watching are the ones directed by Rodriguez and Tarantino.
