Alex Gibney

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

(On Der Würgeengel (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.
