Factual error: The USS Sawfish is supposedly a nuclear powered submarine, but the shots of her entering Williamstown show diesel exhaust coming from her. (Apparently they had to substitute an Australian diesel-electric submarine).
On the Beach (1959)
1 factual error - chronological order
Directed by: Stanley Kramer
Starring: Gregory Peck, Fred Astaire, Anthony Perkins, Ava Gardner
Other mistake: According to the plot, no life is possible in the Northern Hemisphere by the time the film is set. Yet, when the sailor who has been sent ashore to look around the San Diego refinery enters the premises (more precisely, when we see the smoking-prohibited sign on our right and his left) a bird can be seen flying in the upper left-hand corner of the screen.
Morgan: They pushed us too far! They didn't think we'd fight, no matter what they did.
Julian Osborne: And they were wrong. We fought. We expunged them. And we didn't do such a bad job on ourselves.
Trivia: When Moira and Bill Davidson are strolling in the pasture, they pause to admire a beautiful mare that is posing for them, and Bill offers the horse something to eat from the palm of his hand (sugar cubes or some other treat, presumably, but it's not visible). However, the horse does not react to the treat nor eat anything that Bill offers, because the actor's hand was actually empty. The trained horse was obeying cues from her trainer, off-camera, and only her trainer carried the real treats.
