Continuity mistake: When Fausta helps Wonder Woman and Steve escape, they climb the rope out of the water. Steve's pants are obviously wet as he's climbing the rope. However, when he climbs over the side of the well, the camera angle changes and his pants are magically dry.
Continuity mistake: Wonder Woman reveals her belt gives her superhuman strength. In the scene where she is strapped to a board, the Nazi officer throws the belt and lasso at Wonder Woman, but she only catches the lasso. Wonder Woman still regains her strength though and breaks free of the straps. In the next shot however, she is holding both the lasso and the belt.
