Alex Gibney

Dedicated his Oscar win for Best Documentary for Taxi to the Dark Side (2007) to Dilawar, the 22-year-old Afghan taxi driver on whom the documentary is based.

(On El ángel exterminador (1962)) It's dark, but it's also wickedly funny and mysterious in ways that can't be reduced to a simple, analytical explanation. I always thought that's what's great about movies sometimes- the best movies have to be experienced; they can't just be written about.
