Revealing: 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: When Gus goes back to Clyde's dead body, he rolls him in the body bag and you see Clyde's one eye shut. But when he zippers up the bag Clyde's eye is open.
Continuity: Right after the bully has been killed by the motorcycle, in the wide shot, everything from his forehead to his chest is a totally mangled, disgusting mess. A little while later, though, in the close-up, his face, although bloody, is completely intact and recognisable.
Continuity: 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.
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.
Continuity: 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.
Continuity: When Jeff's mom is killed on the set, there are distinct burn marks on her face from the cage, but when she comes back, her face looks pretty smooth.
