Robert Rodriguez is a multi-talented man. He got his start doing crazy low-budget films and has kept that jack-of-all trades style as he's moved up in budget and scope.
His breakout hit was El Mariachi, which he made for, literally, pocket change for the Mexican market. It's in Spanish, but it's a decent mistaken identity action movie.
He works fast and he works cheap. His movies have not been massive hits, but he know the business well and his movies make money since he uses a fraction of the budget of most directors.
One of the more unique filmmakers out there. Surprisingly few have been able to follow the trail he blazed in the 90s.
The man behind the Mariachi trilogy, From Dusk Till Dawn, Sin City and soon Grindhouse. A director with a keen eye for images, style and filmmusic. One of my favourite directors. I don't get the Spy Kids thing though...
