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)
Deliberate mistake: Steve is not superhuman, but he could see and almost (Diana whips it out of the way first) dodge a bullet at the beginning of the car chase. (01:21:55)
Factual error: Diana decides to attend the party Lord invited her to. The music played as she makes her way through the various sleazeballs is "Welcome to the Pleasuredome" from Frankie Goes to Hollywood's eponymous album, which was released in 1984 yes, but just on October 29th, and almost a whole year later as a single. The movie takes places around 4th of July. (00:41:05)
Character mistake: Greeting Steve in his gardens, the Emir says "Your fortune the last few days has been impressive to say the least." It literally happened overnight, not 'days'. (01:16:50)
Factual error: Diana is having a romantic walk with the newfound Steve by the Reflecting Pool, walking towards the Lincoln Memorial. Behind them there's the imposing shape of the Washington monument, but also lit in the night are the columns of the World War II memorial, which was built entirely in the new millennium. (00:46:50)
Factual error: The metro scene shows signs for the green and yellow lines. The green line didn't open until 1991. The scene also showed an electronic sign that shows the time until the next train. These weren't installed until much later than 1984. (00:57:50)
Factual error: When Max is driving off with the egyptian Emir's former security team, they are driving cars that have license plates with numbers and letters. In the '80s, Egyptian license plates were in a numbers only format. (01:19:20)
Continuity mistake: In a mistake endemic of dinner scenes and conversations in general, the hand position of Diana by the glass keeps changing between shot and reverse, multiple times. (00:25:50)
Revealing mistake: Wonder Woman tosses from the shopping mall building the four criminals neatly wrapped up in a banner. The guys smash in their fall the roof of a police car, and they softly bounce as if they landed on a mattress. (00:17:00)
Factual error: The plane that Diana and Steve steal from the Smithsonian appears to be a mix of the fuselage, wings and tail of a Panavia Tornado F3 and the cockpit of an F-111 Aardvark. This class of aircraft has a maximum range of about 1,000 miles, meaning they would never have been able to fly it to Egypt without refuelling. Given that they stole it, it's unlikely they would have been able to call in an offscreen refuel during the flight.
Other mistake: It's amazing the guy whose body Steve is inhabiting gets into the party. Clearly it's VIP and formal dress while he's dressed in casual clothes.
Other mistake: In the first Wonder Woman movie, Queen Hippolyta, Wonder Woman's mother, was adamant that Diana was never to be trained as a warrior, fearing the fact that making her stronger would draw Ares to her (or vice versa), and argues with her sister who was training her in secret when she finds out; this incident happens when Diana is an adolescent. In this movie, a much younger, still child-like Diana takes part (and nearly wins) a contest between the fiercest athletes, involving horseback archery. The Queen should be freaking out and look for whoever put a weapon in her kid's hand, and instead she is perfectly happy, obviously cheering for her and at the end she even gives her a pep talk telling her to look up to...the great warrior Asteria.
Character mistake: Diana losing the race is presented by the movie as some sort of a judgement call from her aunt who tackles her as she is about to finish, to punish her for cheating taking a shortcut. "But I would have won!" she cries, and her aunt explains to her that it would have not been right. Simply put...No! That's not the case; the movie itself shows that Diana missed a checkpoint, which are recorded and represented visually in the main stadium by flags being unrolled each time one is reached. She did not take a shortcut, she went through the wrong path. (00:08:05)
Revealing mistake: Diana saves the kids, with the kids being dummies so obvious to spot it's not even funny. (01:25:40)
Continuity mistake: When the flashback with Asteria is shown she's got hazel or green eyes. In the post credits scene when played by Lynda Carter she's got light blue eyes.
Suggested correction: It should be noted, Lynda Carter played both parts. Those are literally Lynda Carter's eyes we see in the flashback.
Still doesn't explain why they are green in the flashback. Lynda Carter has blue eyes. Probably caused by a color filter.
It could be a lighting issue or the way the armor made her eyes look different, but it's not a mistake since it's the same color eyes. (There are optical illusions that make some people see one color as two different colors based on the surrounding color).
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)
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. (00:57:50)
Factual error: The mall robbery happens on July 1st, as shown on the newspaper clipping Diana finds, which is coherent with the events depicted in the movie (they rob the mall on the 1st, the day after the stone is at the Smithsonian and Diana and Barbara bond over dinner, then on the 3rd Maxwell arrives, grabs the stone at the evening party, and he is already super powerful the afternoon he takes off for Cairo). Problem is, July the 1st was a Sunday, and not just the mall, but pretty much any other store downtown is open, and similarly since it's the 4th, financial operations wouldn't be happening (although in this case you could always argue that we deal with wishes - but it's an extra layer of implausibility). (01:04:05)
Continuity mistake: When young whiny Diana is being consoled by her mum, Connie Nielsen has the thumb on the top of Diana's shoulder either through hair or free from it, depending on the shot. (00:10:30)
Other mistake: To win the race, the 9 Amazons need to shoot color coded targets from a wheel that has 7 possible 'arrows'. That seems already rather impossible, since the colors are unique to the contestants. Moreover, Diana's color, blue, is consistently on top in the 12 o'clock position, but their rivals' insignia in yellow and red change position, adding an unfair advantage to the heroine, or to be precise, they are at 10 and 2 the first time, 4 and 7 the rest of the time. (00:05:55)
