Revealing mistake: Rusty Cameron makes a call from a pay telephone. He makes several movements with his index finger and the sound of the dial can be heard but the dial itself never moves.
Factual error: When the two escapees from the POW camp are in the anchor room of the ship they are on, they leave the harbour and the pilot boat leaves them, but then the chain for the anchor goes out, but they are moving away from the port, why on earth would they be dropping the anchor? If anything they would make sure that all the chain is in the anchor room and the anchor would be on deck.
Continuity mistake: Upon seeing Donald Duck's footprints in the sand, Chip walks the length of one footprint, leaving eight of his own footprints as he goes. He fetches Dale to show him Donald's footprints but when Chip reaches the footprint he walked across, his own footprints have vanished.
