Visible crew/equipment: When Wonder Woman's going under the truck during the desert chase, look closely and you can see the mechanic's creeper the actress is lying on.
Wonder Woman 1984 (2020)
1 visible crew/equipment mistake
Directed by: Patty Jenkins
Starring: Chris Pine, Robin Wright, Gal Gadot, Pedro Pascal
Factual error: When Diana first brings Steve into the DC Metro, the modern-day signage visible inside L'Enfant Plaza Station is not era-appropriate to 1984. It includes markers for the Green Line (opened in 1991) and Silver Line (opened in 2014), and all markers are shown with printed abbreviations, which were not added until the Silver Line opened. (00:57:49)
Diana Prince: Nothing good is born from lies. And greatness is not what you think.
Trivia: Panning around Diana's apartment, the camera briefly lingers on a photo of her with an elderly lady, with no elaboration of its significance. But look closely and you'll realise the woman in the photo is Etta from the first movie, again played by Lucy Davis, just made up to look 67 years older.
Question: How did Antiope know Diana cheated? Why allow her to compete in this contest if she wasn't allowed to train, at first, in the previous movie?
Answer: In the first movie, Diana was much younger and unready to start combat training. In the second movie, the flashback scene takes place some years after that, and Diana has since grown and been in training. During the competition, there were observers along the entire course to ensure that everyone followed the rules, attended to any mishaps, etc. If anyone cheated or failed to complete the required tasks, it would immediately be reported to Antiope.
Answer: The competitors had to light up the cloth banner beacons using their bows and arrows. Diana finished the course but missed one blue beacon by taking the cave shortcut, so the general grabs her and disqualifies her.
