The New Original Wonder Woman - S1-E1
Other mistake: Watch when Diana is looking at the newspaper. The headline reads "Steve Trevor Recovering Well, Now Able to Speak", but the story is something about a US Envoy and has nothing at all to do with Steve Trevor.
The New Original Wonder Woman - S1-E1
Other mistake: When Wonder Woman and Marcia are fighting, Marcia's high heel platform shoes change into different shoes, minus the platforms.
The New Original Wonder Woman - S1-E1
Other mistake: After Von Blasko has given Drangel his orders Von Blasko wishes him "good hunting," and when it cuts to the shot of the aircraft taking off, we see the backwards number "5" revealing it's a flipped shot.
The New Original Wonder Woman - S1-E1
Other mistake: The newspaper reads "Major Steve Trevor Dies in Crash", followed by a single paragraph, then the story is about something completely unrelated.
Wonder Woman Meets Baroness Von Gunther - S1-E2
Other mistake: When Wonder Woman is chasing the Baroness, she lassos her with her magical lasso. When she gets the lasso around the Baroness, Wonder Woman tugs on the lasso, but this pushes the Baroness in the exact opposite direction and into the swimming pool. Just before she falls in, you can even see the tension from the tug pulling her in the opposite direction, yet she falls in the opposite direction anyway as if she's been pushed, not pulled.
Wonder Woman Meets Baroness Von Gunther - S1-E2
Other mistake: After Wonder Woman rescues Steve and another soldier from the burning Old Virginia Stables, in the next shot the textbox onscreen reads, "Shortly therafter in Diana Prince's apartment," but the proper spelling is "thereafter."
The Feminum Mystique: Part 2 - S1-E6
Other mistake: When Captain Radl is parachuting into the water, the episode's onscreen textbox reads, "Elsewhere in the Carribean, a Nazi rendezvous is occuring," but the proper spelling of the words are "Caribbean" and "occurring."
The Feminum Mystique: Part 2 - S1-E6
Other mistake: This takes place during WWII, but during scenes revolving around the XPJ-1 at Aldridge Field, there are modern 1970s vehicles which can be seen all over the airfield in the background of some shots.
The Feminum Mystique: Part 2 - S1-E6
Other mistake: On Paradise Island, while the Nazis are distracted by the quarreling Amazons in the water, when Wonder Woman jumps and lands beside Queen Hippolyta her boots are flat, but the heels soon appear when she rushes off with the bracelets. This happens again later, when Wonder Woman chases after the XPJ-1 on the runway.
Other mistake: This takes place in 1942, but modern 1970s era cars can be seen behind Wonder Woman and Steve when the attendants are loading Benson into the ambulance. Then again later, when The Falcon's partner creates a diversion and is being shot at by the guard.
Other mistake: When the two dollar bill engraving plates are being stolen from the Bureau of Printing and Engraving (in reality it's called Bureau of Engraving and Printing), in the closeup of the plates we see the obverse and reverse sides do not look like the images on real two dollar bills of that era (perhaps this was deliberate, but still an error).
Other mistake: When Diana and Etta have their picture taken by Wotan in disguise, Diana makes eye contact with Wotan and in the extreme closeup of Diana's eyes we see that Lynda Carter is wearing modern contact lenses under her eyeglasses.
Other mistake: After Wotan's arrival on the Virginia beach, there are two closeups of Wonder Woman leaping into the air and the "boots" she's wearing aren't actually boots, they are shoes with the high boot part layered over them, and when she's on the beach she's wearing the flat boots.
Other mistake: In the two closeups of Steve's two dollar bill being held first by Steve and then by Diana, we can read "1963 A" and the name "Henry H. Fowler" Secretary of the Treasury during Lyndon Johnson's administration, as it appears under the red seal, even though this takes place in 1942.
Formula 407 - S1-E12
Other mistake: At the start, the episode's textbox reads, "Fort Frazier Ordnance Testing Facility" with correct spelling, but in the next shot the base's sign reads, "Fort Frazier Ordinance Testing Facility" when it should actually be "Ordnance."
Wonder Woman in Hollywood - S1-E14
Other mistake: When Wonder Woman and Wonder Girl are at Bremer's estate to find Steve and Jim, Wonder Girl's lasso hangs either on the left side of her belt or on the right side, depending on the angle of the shot.
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.
