Visible crew/equipment: After Lampkin tells his buddies to deal him into the poker game and how they'll clean out Diamond H cattle, when it cuts to the Maria and Charlie doing dishes, there is something at the left side of the screen that moves with the camera, which should not be seen onscreen (widescreen version).

The Return of Wonder Woman - S2-E1
Factual error: When Steve gets attacked by the bad guys and Wonder Woman shows up, the lady in the car pulls out a camera and films the event. She sits still, the car isn't moving, and she does all the filming from the same position. However when she watches the playback, the film shows footage from multiple angles and varying distances, which is impossible because she and the camera were in the same spot the whole time.
Answer: The transformation twirling was invented for the 1970s TV series only, to explain her quick change from Diana Prince to Wonder Woman. However, it would have been nice to do a little spin homage in the movie.
