The two-second recurring shot of a picture frame falling off a door took half a day of filming to get right. This is due to the fact that: 1) The rigging of the frame was more secure than anticipated, resulting in the picture frame not becoming dislodged as planned; 2) The aggressive knocking on the door caused it to repeatedly become dislodged from its hinges, and; 3) The Director kept accidentally rolling into shot on his skateboard.
