Quentin Tarantino because Reservoir Dogs was the first film I saw were I realized I could truly turn my loves of movies into a career.
Robert Rodriguez for El Mariachi which shows you can make a cool movie for a low budget and for his book Rebel Without A Crew.
Those two always inspire me and show me one day I will make it.
I am also inspired by the work of David Lean, Steven Spielberg, John Ford, Akira Kurosawa, John Woo, Michael Mann. Those are my role models and heros.
