Revealing mistake: After Christine gets out of the shower, we hear the director cue her by saying, "Go," before she walks past the camera.

Revealing mistake: As the Spleen and Invisible Boy stand silhouetted in front of the moon, their motions are easy to tell as the film being run forward and backwards.
Revealing mistake: In addition to the chain and lock not being in a position to actually secure the entrance to the "Metro Christian Shelter", the board covering the entrance does not appear to be securely attached to the building on the right side. Furthermore, when the men move the board over, it is a rather thin piece of plywood/board that can easily be kicked in. (00:17:17)
