John C. Reilly: Rock Star

A mock rockumentary starring John C. Reilly as a drug-addled rock star who has more ups and downs than a yo-yo? With a script by Judd Apatow and Jake Kasdan, a focus on the 50s through the 70s and songs by the likes of Marshall Crenshaw and music from Van Dyke Parks? They haven't even started filming and I'm already eager to go see it.
