Other mistake: Since Max renounced his wish, it is implied and shown that he had to give up also all the benefits he gained from his role, still he uses the Marine One presidential heli to get back to land. There's also no way he'd know where his son was, considering that in the lasso's vision he was running on a highway, and he happens to find him at the White House lawn. (02:20:00)Sammo
Continuity mistake: Barbara kicks the Dangerous Drunk one last time, and we see him fall with the feet next to the curb of the sidewalk. The man is still conscious and tries to move, seemingly to crawl forward, but we do not see him even budge, and when Leon the cultured hobo arrives mere seconds later the guy is unconscious and can't even move, but he's in the middle of the road now.

Deliberate mistake: When Diana and Steve visit the Mayan guru hideout, they find an issue of Pro Wrestling Illustrated with Jerry Lawler on the cover. It's the August 1984 issue though, that couldn't be there since it's still early July. The prop department knew what they were doing there though; if you look at the cover, you can see they modified it and it actually says July 1984. (01:29:40)Sammo
Factual error: Past the escalator, Steve and Diana walk past some literal punks who are wearing T-shirts. Some are appropriate for the period (such as the Bad Brains one, their debut album is from 1982) but the one with the cheetah leggings is sporting a Cro-Mags T-shirt; their debut album "The Age of Quarrel" (and its artwork is on the T-shirt itself) was a September 1986 release and this unfortunately isn't Wonder Woman 1986.

Plot hole: Wonder Woman says they can't fly commercially because Steve Trevor doesn't have a passport. Except the movie established that only Wonder Woman sees him as Steve Trevor. To the rest of the world he's still the man whose body Steve has inhabited, so there's no reason he can't use his passport.
Other mistake: Fireworks use heated metals to produce the various colors seen when they explode - Iron, Nickel, Cryolite, magnesium and copper filings. Flying a jet engine through exploding fireworks would cause serious damage to the engine.
Factual error: The video games Operation Wolf and Rampage were visible in the Family Amusement Center arcade during the opening. However, this would not be possible during the movie's 1984 setting since Rampage wasn't released until 1986 and Operation Wolf wasn't released until 1987. (00:12:48)AD
