Continuity mistake: A neighbor reminds Tom Diaz that several plastic balls and rubber balls are stuck in the rain gutter. Diaz looks up and sees eight balls in the gutter. Later, when Diaz accidentally backs his car into a post and dislodges the rain gutter, approximately 20 balls fall. In addition, several of the balls are shown rolling off the edge of the roof. They were obviously not in the gutter and instead were dropped by a stagehand.
