The bartender is named Red because he gets everything for everyone, like Morgan Freeman's character in Shawshank Redemption. This becomes a major plot point in "The Insomniac."
In the office scene, Paul tells John, "You have finally made my shit list," a reference to "The Machinist", in which Tucker tells Trevor the same line.
In the bar scene, behind John and Martha is a small sticker on the wall from the movie "Skills Like This", which was Monty Miranda's directorial debut and stars Spencer Berger (Andrew in "The Insomniac").
