Things can get interesting in a love triangle but, for most of us, not as interesting as they get in our dreams. Expect a Buster Keaton character to have a most alarming slapstick dream.
If you like the films of the silent comedians, Sherlock Jr. (1924) is one of the best. It is, in fact, a nearly perfect cinematic farce—a farce replete with terrific sight gags and, at 44 minutes, utterly without filler. Keaton had no hand in writing it, as he did some of his other films, but as actor and director he was an undeniable master of execution.
