Continuity mistake: When Wonder Woman is spinning the XPJ-1 around, she's seen approaching the jet with her hands empty and her lasso on her side where it usually is. As the scene progresses, her golden lasso magically appears in her right hand even though she never reached down to pick it up.
Revealing mistake: When one of the Nazis brings Drusilla a hot meal while she's being held in the deserted warehouse, in the shot just as she whacks him in the stomach we can see the stunt cable over the Nazi (stunt double) which lifts and pulls him back.Super Grover
Continuity mistake: While Nazis are invading Paradise Island, back at the deserted warehouse when one of the Nazis brings Drusilla a hot meal he slams the door shut, but when Drusilla hits him in the stomach the door is suddenly wide open, but when she rushes out of the room the door is closed and she pushes it open.Super Grover
Other mistake: On Paradise Island, while the Nazis are distracted by the quarreling Amazons in the water, when Wonder Woman jumps and lands beside Queen Hippolyta her boots are flat, but the heels soon appear when she rushes off with the bracelets. This happens again later, when Wonder Woman chases after the XPJ-1 on the runway.Super Grover
Visible crew/equipment: After the Nazis are defeated on Paradise Island, Queen Hippolyta tells her daughters that she has plans for those Nazis, and at the start of the next shot a bit of set equipment can be seen at the left side of the screen (widescreen version).Super Grover
Visible crew/equipment: During the Nazi rendezvous aboard the destroyer in the Caribbean, when Captain Radl and the other Nazi walk into the ship's stateroom, both unfinished ends of the set walls can be seen at the left and right side of the screen (widescreen version).Super Grover
