Generally, comedies are pretty cut and dried when it comes to their endings, but this one is a bit of a thinker, especially because the ending is a little unclear. The film has Dustin Hoffman as Benjamin, a recent graduate, who’s seduced by an older woman, but instead falls in love with her daughter, Elaine.

When we get to the ending, you see the very famous scene where he crashes Elaine’s wedding by banging on the glass at the church. The two escape by flagging down a bus, but the last shot of the film has both Elaine and Ben, sitting there with a shocked and uncertain look on their face. Some say it’s a look of regret and “What did we just do?” Others say that they’re just relaxing and relieved that they’re going to get away with it.
