Factual error: When Holland March is swimming behind the bar with mermaids, "Get Down On It" from Kool and The gang is playing. That song did not come out until 1981 and the film is set in 1977.(00:39:50)
Holland March: Look on the bright side. Nobody got hurt. Jackson Healy: People got hurt. Holland March: I'm saying, I think they died quickly, though. So I don't think they got hurt.
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.
