Where Credit's Due is the fourth episode of the sixth season. It was released on 16 October 2009.
The team gets a close-up look at the movie business when a producer's desiccated body is found in the desert. Elsewhere, Larry knows that he's leaving but not his destination, and Alan struggles with technology, and his place in a new, ever-changing world.
The full expression is "Credit where credit's due", meaning that one acknowledges someone else's vital contribution to a process, or even leading role therein. Here, it's connected to the credits of a movie, the opening and closing acknowledgement of contributors.
