Continuity mistake: Benjamin runs up the steps to his apartment to find Mr. Robinson sitting there waiting for him. Before he gets to the door the wall on his right is dark but then in the next shot as we see him entering the apartment that wall is totally lit up. (01:30:35)

????

Continuity mistake: As he leaves the apartment Mr. McCleery tells Benjamin to, "get out of here". If you look closely at the light fixture over the pay phone in front of him you'll see it only has one light on it. In the next shot as he rounds the staircase we see it again and there are two lights on it. (01:33:15)

????

Continuity mistake: Mrs. Robinson runs into the house after Benjamin and the chair and plant at the bottom of the steps on the left of the screen have been moved without anyone being near them. (01:09:05)

????

Continuity mistake: 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. (01:41:30)

????

Continuity mistake: The two large black liquor bottles that were on the left of Mrs. Robinson's bar when they walked out have been moved several feet to the right as Mr. Robinson pours Benjamin a drink. (00:12:10)

????

Continuity mistake: Benjamin says to Mrs. Robinson, "I'm going home now, I apologize for what I said" as he walks out of Elaine's room. In the next shot as Mrs. Robinson walks out, if you look very closely everything on the three shelves to the left and right of Elaine's picture has been rearranged. (00:15:00)

????

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 and his mother have a conversation in the bathroom as he's shaving and he cuts his thumb on the razor. If you look closely the part of his thumb that's cut is nowhere near the razor, only his thumbnail is. (00:45:10)

????

Continuity mistake: We see Benjamin's fish tank as Mrs. Robinson barges into his room looking for the bathroom. It's rearranged between shots, with the deep-sea diver in the middle removed. (00:07:00)

????

Continuity mistake: In the hotel room Mrs. Robinson makes Benjamin promise that he will never take Elaine out. If you look closely the purple chair in the middle of the room has been moved out about a foot away from the wall so that it's now blocking her line of sight and obscuring the bottom of the lamp that's in front of the window. When we saw this spot before as they were lying in bed the bottom of the lamp could easily be seen from the bed. (00:54:05)

????

Continuity mistake: Benjamin and Mrs. Robinson have a rendezvous and while they're in bed he gets her to talk about where Elaine was conceived. She turns out the light and the conversation continues a while in the dark until Benjamin indicates that he might take Elaine out on a date. She turns on the light again and gets ready to rip his head off and two drinks appear where there were none before under the lamp on the left of the screen. (00:49:40)

????

Continuity mistake: Benjamin and Mrs. Robinson have a rendezvous and while they're in bed in the dark he tries to get her to talk about her life and her husband. If you look closely after she turns the light back on the drapes on the window behind the lamp in the rear of the room have been rearranged without anyone going near them. This happens a couple of times throughout the scene. (00:48:00)

????

Continuity mistake: After Benjamin cuts his thumb on the razor he takes it and curls it under his other four fingers. In the next shot his left hand is open wide and the thumb is not bleeding. (00:45:10)

????

Continuity mistake: After Benjamin and Mrs. Robinson have a fight about Elaine she sits on the side of the bed putting on her stockings as she gets ready to leave. Benjamin says, "Oh no, look I like you" and in the next shot as the camera shifts angles a chair appears in front of Mrs. Robinson that wasn't there before. (00:53:10)

????

Continuity mistake: Benjamin arrives at the Robinson's for his date with Elaine and he sits on the couch next to Mrs. Robinson to try to explain. Before he sits down the lamp on the left of the couch is off, then in the next shot as he sits down the lamp is on. (00:57:00)

????

Continuity mistake: When Mrs. Robinson first walks into Benjamin's room there's a dual light switch on the wall to the left the door that disappears two shots later as she walks across the room. (00:07:10)

????

Continuity mistake: Before Mr. Braddock introduces Benjamin at his birthday party we get a good look at the lawn chairs on the left of the screen and they're all in the shade. Several shots later when Benjamin finally comes out in his Scuba gear the lawn chairs are in the sunlight. (00:21:55)

????

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)

????

Continuity mistake: Benjamin and Mrs. Robinson have a rendezvous and while they're in bed he tries to get her to talk about her life and her husband. If you look closely at the top of the nightstand to her right there's only a pack of cigarettes and the switch to turn off the lamp. They speak in the dark for a few seconds that she turns the light back on and the nightstand is full of all sorts of other stuff that wasn't there before. (00:46:15)
