Rick Schwartz of Grantland on Executive Producers:
Though it sounds more important than its predecessor, this credit is the consolation prize when you don’t get the big one. E.P, as it’s known, often goes to people who put up a lot of the actual financing but wouldn’t know a good movie if Spielberg showed up at their house with a Super 8, Tom Hanks, and a giant robot.
Schwartz’s piece covers (in a somewhat snarky way) the difference between a Producer, Executive Producer, Co-Producer and Associate Producer. If you have ever been curious, it’s definitely worth a peak.
