Visible crew/equipment: When the truck carrying the caged gorilla pulls into the alleyway, just as Hans and Carl exit the truck and walk away, the blue-sleeved arm of the cameraman/crew member is visible as it moves upward, at the right side of the screen.Super Grover
Continuity mistake: After the Nazis capture Steigler, while they're at the oil refinery Gargantua is in a cage behind them, and when Erica blows the whistle the gorilla reaches through the bars and grabs a large cardboard cutout of Wonder Woman, which was leaning against the wall, but the problem is that in the previous shots that cardboard cutout was not there.Super Grover
Visible crew/equipment: While Wonder Woman searches for Steigler at the deserted oil refinery the Nazis force Steigler to shout for help, then when they all hide and Wonder Woman breaks into the room, the actors' two tape marks can be seen on the floor near Steigler.Super Grover
Revealing mistake: While the circus crowd is gathered around the cage with Gargantua, there's a closeup of the gorilla as he roars and we can see the stuntman's human teeth behind the gorilla's teeth. It happens again in Gargantua's closeup while he's climbing up to Steigler's window.Super Grover
Continuity mistake: When Wonder Woman arrives at the warehouse where Steigler is being held, as she's using her lasso to scale the building the high heels on her boots have vanished, and they're now flats. This switch also occurs in previous shots, as well as at the start when Erica Belgard is disguised as Wonder Woman.Super Grover
Revealing mistake: After Erica shows Gargantua the window of Steigler's location, when the gorilla climbs up the building we can see the end of the hairy sleeves, and the wrists/hands of the stuntman in the gorilla suit. Then on his way down we can see the end of his hairy pants at his ankle.Super Grover
Continuity mistake: After Gargantua slams Steigler into the desk, Steigler's body can barely be seen on top of the desk and looks like most of his body is behind the desk. However, when the MP enters the room, Steigler is shown to be on top of the desk and his whole body can be seen. Gargantua didn't move him and Steigler is unconscious.
