The film was sealed with a kiss for Elwes.

On Nov. 21, Elwes filmed his final scene: the now-famous movie-ending kiss between Westley and Buttercup. In the book, Goldman wrote, “Since the invention of the kiss … there have been five kisses that have been rated the most passionate, the most pure. This one left them all behind.”

For Reiner, it took six takes to get the kiss right. “I could have gone on shooting that scene all day, as I don’t think I wanted the movie to end,” Elwes wrote. “It was also a very tender way to end the movie. Sealing it with a kiss, so to speak.”
