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: The line "he'll stop doing it" "stop doing what?" followed by violence was used almost identically in Iron Man 3, also written and directed by Shane Black.
