Continuity mistake: When John Mills is looking through the periscope whilst searching for the German battleship the side view shows him moving the periscope from right to left, but when it suddenly cuts to a shot of what he is actually seeing through it the periscope is strangely moving from left to right.
Continuity mistake: In the scene where the tank crew meet up with the weary band of soldiers, Fred Clarkson (Lloyd Bridges) has a very distinctive graze on the right side of his forehead. It seems to disappear then appear then disappear during the film. When Clarkson lies injured there is no sign of the graze - there should at least be a small mark of the graze but there is nothing.
Continuity mistake: In the scene where Tarzan rescues Connie from a lynching, Connie jumps onto the horse ridden by Tarzan with her hands firmly tied behind her back. They then ride into the desert followed by their captors. A close up shot shows Connie is untied and is holding onto Tarzan. In the next few shots Connie's hands are once again tied behind her back.keiko
