Working with digital...
Found this through io9. A trailer for a documentary (Side by Side) by Keanu Reeves about the transition to digital photography (and the rise of 3D) from the point of view of directors. It seems to feature interview footage from Scorcese to Nolan! Looks interesting (but maybe I'm just a geek that way.)
