Trivia: The corpse of Sid Shattuck, which Ryan Gosling discovers after his drunken roll down the hill, is played by an uncredited Robert Downey Jr., who'd previously starred in Shane Black's "Kiss Kiss Bang Bang", a film which played a large part in revitalising his career after drug and legal issues.

Trivia: When Mr. Jimmy is calling out names on the boat to see who's missing, the real Mr. Jimmy Harrell is standing next to him, wearing a dirty grey T-shirt (and presumably playing a random rig worker).
