Corrected entry: Benjamin runs up to the front door of the church and finds it locked. This may be a deliberate choice of the director because they need a reason to get Benjamin up to the second floor window so they lock the front door of the church. It's not locked when he leaves the church.
Corrected entry: In the opening scene, Benjamin has returned to Los Angeles from college and is riding a moving walkway through the airport. Although the tag on his bag says LAX (the airport code for the Los Angeles International airport) that airport has never had a moving walkway.
Corrected entry: In one scene Ben and Elaine are supposed to be at UC Berkeley, but the buildings visible in the background are actually the Doheney Library and the Von Kleinsmid Center, which are located at the University of Southern California in Los Angeles.
Corrected entry: Towards the end of the movie, Ben returns to Elaine's home after she quits school and finds her mother in her room. He rushes off in his car to stop Elaine's wedding in Santa Barbara and is confronted by the people attending the wedding, including Elaine's mother. Mrs. Robinson couldn't have gotten there before Ben did.
