Directors Martin Scorsese and James Cameron have different ideas about the use of CGI in film:
“My big concern is that the image, ultimately, with CGI, I don’t know if our younger generation is believing anything anymore on screen. It’s not real.” - Martin Scorsese
“When was it ever real? There was kind of a wall there and nothing over there. There are 30 people standing around. There’s a guy with a boom mic, there’s another guy up on a ladder with his ass crack hanging out. There’s fake rain. Your ‘street, night exterior New York’ was a ‘day, interior Burbank’. What was ever real?” - James Cameron
This was a good documentary, Keanu asked good questions.
