Trivia: A change from the theatrical re-release for the 25th anniversary and the video release. In the first Taft Hotel bedroom scene, a nervous Ben asks Mrs. Robinson if she would like "Wood or Wire [hanger]?" In the theater, her response was, "wood." Which led to the wonderful pratfall of Ben trying to take the wood one, which wouldn't come off. But it was changed in the 25th anniversary video release and her response was, "Either one would be fine."
Trivia: When Ben rings up Mrs Robinson, to ask her to have sex with him in the hotel, and she says she'll be thirty minutes. While waiting for her, Ben goes into the ballroom, where an affair is taking place. The two women who greet Ben are both regulars in the TV series "Bewitched"; the first is Alice Ghostley, the nosy neighbour, and the second is Sam's whacky aunt who often lands in the fireplace, when her radar for landing spots goes mad, again.
