Factual error: There is a scene with Dustin Hoffman going to Berkeley but his car is driving on the upper deck of Bay Bridge which only goes in the direction of San Francisco.

Plot hole: In one scene, he's driving from Los Angeles to Berkeley in a hurry, and crosses the bridge again (in the wrong direction). But the most direct route from L.A. to Berkeley doesn't require you to cross the Bay Bridge in EITHER direction.

Continuity: As Mrs. Robinson walks into Benjamin's room we see his dart board and someone has been playing between shots as the red dart above the board on the wallpaper moves six lines to the left.

Continuity: Benjamin runs around the side of the church then up some steps in order to get in. When we first see the second floor entrance it's in bright sunlight then in the close-up as he gets to the door it's not.

Continuity: When Benjamin is running up the stairs of his rooming house with a stack of presents and a big bouquet of flowers, the flowers are pointing down held by his left hand with the presents in front of him. When he rounds the corner of the stairs, the flowers are upright in front of both him and the presents.
