Revealing mistake: After he bangs on the second floor church window, Elaine screams his name and Benjamin runs down the steps to the main floor of the church. Mr. Robinson meets him halfway down as they fight and if you look closely Benjamin's white windbreaker was made to just fall apart as Mr. Robinson tugs on it. (01:43:00)
Revealing mistake: Benjamin pulls into a gas station to use the phone near the end. There are an awful lot of tire marks where the car skids to a stop. Likely practice marks from previous takes.
