Factual error: The movie takes place in 1977. A boy tells his father he is playing PacMan, which came out in 1980. Then we see a cabinet of Ms. Pacman, which came out in 1982.
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.
