When Diana and Steve arrive at the Smithsonian air museum to steal a plane, the Panavia Tornado jet they steal is first shown with its correct inline seating configuration from the exterior, but once they climb inside, it switches to a side-by-side seating configuration.
During the Egyptian road chase scene while rescuing the children Wonder Woman loses her grip on her lasso and falls but as soon as she hits the road it is all neatly looped back onto her belt again.
When Diana and Barbara are having an early lunch the shot starts off with food on the table then it disappears after a few moments.
In the Egypt car chase scene, when Diana says, "I've got this," her red, blue, and gold suit can be seen under her white shirt. In shots leading up to this, her white shirt is open and the suit is clearly not there.
When Barbara encounters the drunk harasser the second time, she kicks the guy and his key chain falls out on the ground. But when she approaches to kick him again, there was no sign of it.
Modern fighter aircraft take hours to prepare for flight, and are not left fully fueled on museum runways. This plane, which appears to be "based on" the British Tornado strike jet, could not make it to Cairo from Washington DC without refueling. Lastly, modern military aircraft take months, if not years, of training to operate.
Barbara jumps between Max and Steve to "break" the handcuff. In reality, doing that would cause considerable damage to both men's wrists.
When Steve and Diana fly through the July 4th fireworks in a jet plane, the speed is too slow for a jet with two engines. The minimum speed for a jet is 200 kph and the scene should fly past much faster than this speed.
The credits incorrectly thank the Smithsonian Institute. The correct name is the "Smithsonian Institution".
Steve says he just used the phone book to find Diana. He is from 1918. Telephone directories in book format have been around since the 1880s.
Computers in 1985 weren't capable of receiving a TV signal without specific hardware.
At 1:09 Diana uses her magic to make the plane invisible so it can't be detected by radar. However, radar is a detection system that uses radio waves to detect objects. Invisibility alone would not make an object undetectable by radar. To be undetectable by radar, an object would need to be intangible. However, this is not necessarily true. Radar works by use of radio waves being transmitted and bounced back to the point of transmission at the speed of light. Visible light waves work on the same principle, and are bounced off objects so that we can see them with our eyes. Both radio waves and visible light waves are part of the electromagnetic spectrum. Diana makes the plane invisible by using her powers to somehow allow light waves to pass through it, thus making it appear "transparent". There's no reason to doubt her powers could have had the same effect on radio waves too.
Steve calls the plane he's flying in a jet, but Jet airplanes were developed decades after his death. Jet engine were developed since 1908 by french engineer René Lorin and the concept was exposed to public in 1913. A 1910 prototype that failed was created by Romanian engineer Henri Coanda. There were no jet planes in 1918, but it is possible Steve heard about the prototypes and the word may have already been said, used and/or written (in his books for example).
When Diana explains the origin of the Golden Armor to Steve, she tells him that it belonged to the greatest Amazonian warrior Asteria, but in Wonder Woman (2017) Hippolyta refers to Antiope as the greatest Amazonian warrior. This accolade is understandable, given the Amazon's belief that Asteria died protecting their escape to Themyscira, leaving Antiope as the new 'greatest' warrior.
The children Wonder Woman save from the road are replaced by obvious dummies when she falls and rolls on the ground.
While flying in the jet, Steve and Diana change seating positions, when the camera changes positions from front view to back view.
When Diana/Wonder Woman is sitting in the "studio", watching Mr. Lord asking for the wishes, she leans against a - supposedly - concrete wall that flexes, showing to be actually made of foam or rubber.
When Steve Trevor is driving the jeep while Diana is saving the Egyptian children, you can see Steve's own reflection instead of the man he is possessing from the rear view mirror.
Cut off from the world on an ancient Greek island, Diana and the other Amazons all have shaved legs and armpits.
As Steve and Diana are walking along the national mall, they see a TWA 737 flying south at low altitude. The airspace in this area is highly restricted, and was in 1984, so the aircraft should not be there. In addition, if it were making an approach to National airport (as it was called then) it would be way off course as the runways at that airport are east-west. If it were making an approach to Dulles airport, it would be far too low to make a safe landing there.
In Egypt, the car used by Maxwell Lord is a Mercedes-Benz G-Class W463, which came into production in 1990.
When Wonder Women and Steve Trevor are walking along with the reflecting pool, a shot behind them clearly shows the World War II memorial, which opened in 2004.
Steve Trevor seemed to have learn a lot in his books about jets. This seems impossible and might have made more sense if he had fought in WW2 instead of WW1 like he did in the first set of comics and the Wonder Woman (1975) TV series. Also the maximum range for any fighter jet ever built was the US F-15 Eagle at 5,500 km and the distance between DC and Cairo is 9,400 km, however both Steve and Diana flew that distance round-trip in a jet without refueling.
An assistant brings coffee into the Smithsonian with what appears to be raised plastic latte lids on the cups. More formally known as traveler pucker type coffee cup lids they were not patented until 1986 and did not gain popularity until the 1990s.
While walking through the DC Metro station, Diana and Steve pass a post that lists the directions to the various lines (identified by the line's color and 2 letters). The Silver Line, which did not open until July of 2014, was on the post.
When Diana is fighting Barbara in the White House, Barbara launches Diana to a column which breaks. After that, a piece of another column is clearly thrown on top of Diana, revealing the prop used.
One scene shows a passenger plane landing at National Airport between the Lincoln Memorial and the Washington Monument. All commercial flights fly directly over the Potomac River and would only be seen west of (behind) the Lincoln Memorial, never east (in front of).
Some of the vintage 1980s American cars supposedly in Washington D.C. are recognizable as export models made for the European market, where amber rear turn signals are required and where some D.C. scenes were apparently filmed. These Euro-spec export taillights can most easily be seen on the export Chevrolet Caprice cars made up to be Washington taxicabs.
There are many Agaves visible in the country side during competition at Themyscira. They should not be there, because those plants were brought from America to Europe after Columbus' voyage. Themyscira (in the movies) was closed from all outer influence from c. 1200 BC until AD 1918.
In Justice League (2017), set in 2017 (or perhaps later), Bruce Wayne chides Wonder Woman for withdrawing from the world following the First World War. Leaving aside the absurdity that she would sit out a second worldwide conflict, it is inconceivable that the events of this film would utterly vanish from the public memory in just 33 years.
In Wonder Woman (2017), Hippolyta reluctantly agrees to let a 12 year old Diana be trained as a warrior, however in this movie 8 year old Diana is allowed to participates in a dangerous athletic event against older Amazons and almost wins. She seemed to have mastered archery at 8, she could shoot an arrow while riding a horse. But in the first movie she is still being trained in archery as a 12 year old.
Steve asks about the fireworks as they fly to Cairo. When Diana answers that it is for "the fourth," Steve is surprised and exclaims, "The fourth of July?" Steve is the one who found the ticket in Max's office and says, "If this date is right, he is going to Cairo. How can he get there in one day?" How can the date of July 4 and fireworks be a surprise.
When Diana goes to the empty lab to look at the Dreamstone again, she instead finds a receipt showing the stone was purchased by Maxwell Lord from the Black Market dealer it was seized from.
That night, during the reception, Lord talks Barbara into going to her office, where he steals the stone while kissing her. Later Barbara tells Diana that she loaned the Dreamstone to Lord.

In the shopping mall, Diana destroys the security cameras to keep her secret. This would have not worked. The cameras had already recorded her in action and the tapes are kept in a separate location.
One of the new wonders Diana shows Steve is the escalator and mass transit system. These existed in London during the First World War, where parts of Wonder Woman (2017) were set.
Barbara says of the Dreamstone: "Romulus, the last emperor of Rome, had it on him when he was assassinated in 476." Romulus Augustulus, the last Western Roman Emperor, was forced to abdicate in AD 476, but was not assassinated. He was allowed to go peaceably into exile and live out his days in obscurity. In the novelization of the film, Barbara instead refers to Romulus, the first king of Rome. The first Romulus was a legendary figure, who has not been proven to be historical, so some leeway for revisionist history about his death is permissible in the plot.
The news clipping about the recovery of stolen artifacts from the Washington D.C. mall robbery uses the British/European spelling of "artefacts" in the subhead and throughout the article, although the wording of the story shows it to be from a local Washington newspaper.
Abraham Lincoln didn't have a descendant named Jan, nor any known relative who contributed to the architecture of the White House.
