Continuity mistake: Mr. McGuire asks to speak to Benjamin and takes him through the kitchen where some other people are talking with drinks in their hands. The woman kisses him on the cheek and the man puts his arm around his back but in the next shot they're not even close to him. (00:05:30)

Visible crew/equipment: After he takes her home, there's a rear tracking shot of Benjamin walking Mrs. Robinson down the hallway into the bar area of her house. The shadow of the cameraman's head can be seen on the left of the doorway just after they enter the room. (00:10:10)
Continuity mistake: Mrs. Robinson stands behind the bar and asks Benjamin, "What do you drink?" and you can see the ashtray next to the two black liquor bottles. In this shot there's nothing in it but a few seconds later as she sits in front of the bar it's full of cigarette butts. (00:10:20)
Continuity mistake: Mrs. Robinson sits at the bar and asks Benjamin, "Did you know I was an alcoholic?" and the silver shaker bottle with the large ring on top of it moves from the back of the bar to being between Mrs. Robinson and the radio she turns on, on the left wall. A few shots later it moves back again. (00:11:35)

Continuity mistake: Benjamin says, "I'm going home now" and the red and white plastic ornament above Elaine's bed is casting a shadow on the large "R" behind her head board. In the next shot the lighting is different and there is no shadow. (00:14:50)
