Continuity mistake: In the scene where we see the room from a wider shot there is no rifle leaning against the barrel. We then get a closer shot of a man talking and there is now a rifle leaning against the barrel.
Other mistake: Just after the Royal Navy destroyer has sailed through and depth charged the area where the British survivors are, there is a shot of the churned up sea with sombre music playing, and the seagulls are flying backwards.
Revealing mistake: In the scene where Lancelot runs into and fights Arthur's ambushers, he runs one of them through with his sword. It is visible that he stabs his opponent past the body, but close enough for the appearance.
Continuity mistake: After 1st Sgt. Milton Warden breaks the bottle to stop the fight between Pvt. Angelo Maggio and Sgt. James R. "Fatso" Judson, he throws the bottle in a corner. In the next shot, he's sitting down with the broken bottle on the table in front of him.

Factual error: In the scene where Marcellus is being shipped off to "Palestine" on the galley - presumably from Ostia the port of Rome at the mouth of the Tiber - he is urged to hurry up his farewell to Diana by the galley captain because "we will miss the tide." This is the Mediterranean - there is no tide to speak of.
Other mistake: In the opening credits, Manuel Perez's first name is misspelled as "Manual."
Visible crew/equipment: John Payne leaves a theater after getting into a fight after being tricked by actress friend Evelyn Keyes during an audition.

Factual error: If we are to assume that the British cruisers were Dido class with 5.25" guns, the assertion that the Essen would outrange them by 5000 yards is pretty much true. However, in order for the Brits to launch torpedoes, they would have had to close to inside of 20K yards, well within range of their main guns. Thus said, if the British cruisers were any of their 6 inch gun class, there would have been no advantage in range.

Continuity mistake: When Fred (Ralph Wolf in disguise) says "Hello" to Sam at the end of the short, you can see that there is a card in both the top and bottom holes in the "In" section of the punch clock. But when Sam begins spanking Ralph, the bottom card of the "In" section has moved to the bottom hole of the "Out" section.
Continuity mistake: Before Elmer runs off to fetch his gun, you can see there is a carrot near his feet on the ground. But when he returns, the carrot has gone.
