Louis Psihoyos was for many years a photojournalist before he embarked on making his first film, The Cove, which earlier this week won an Oscar. And in this interview with the National Press Photographers Association (which I used to be a member of), he said this: “It was really refreshing to step outside the journalistic box.” Hallelujah to that. Journalists will always be constrained by facts; filmmakers are free to explore truths.

Once you’ve had a taste, there’s no going back.
