He is jealous, depressed and irritable, and has recently been discharged from an Army mental hospital after his war service in Korea.

Soon enough, Polly becomes a confidante of sorts to George, while Rose's intentions soon become muddier than they seem.Monroe was given first billing in Niagara, which elevated her to star status.

This film contains examples of:
- Anti-Villain: In the end, George is this. The movie states that he was discharged from an Army mental hospital after his war service in Korea, implying that he suffers from the psychological effects of the war, he kills Rose's lover but it's in self-defense because Rose and her lover conspired to kill him, which eventually leads him to kill Rose, and he shows his human side to Polly, even when it's too late for him.
- Decoy Protagonist: Marilyn Monroe's character, of all people, is this. She gets top billing but not only is she the villain, she dies before the climax!
- Inevitable Waterfall: The climax, in which Polly is stuck on a boat moving inexorably toward the lip of the titular waterfall with the mentally unstable George. He pulls a Redemption Equals Death by helping her climb out onto a rock before he plunges lethally over the edge.
- Redemption Equals Death: George's chase eventually ends with him saving Polly from going over the Falls, at the cost of him going over the Falls to his death.
