Revealing mistake: When Gus is putting the kid in the body bag, there is a close up of the kids' faces. Just as Gus is zipping the bag shut the dead kid blinks.
Continuity mistake: When Clyde is with his motorcycle in the woods with Jeff, he is seen putting Jeff's bike wheel to his face. If you look in the background Clyde's motorcycle moves to different positions without anyone touching it.
Continuity mistake: When Chase goes inside Gus's house, there is a sign near the door that says "Rabbits For Sale." But when Chase leaves the entrance the sign is gone.
Visible crew/equipment: In the scene where Gus, Drew and Jeff are sitting at the dinner table, when Gus drops the beans they show a close up of him. In that shot look in the background and you can see a spotlight.
