Revealing mistake: When Wonder Woman (Diana) uses her bracelets to dodge bullets, the many sparks that the bracelets emit, as the bullets hit, are controlled by wired remotes held in Lynda Carter's hands. They are quite visible in her fists in many episodes. Small red bits around the circumference of the bracelets also appear, which provide the flashing spark special effects.
Continuity mistake: Throughout the show Wonder Woman goes from wearing heeled boots to flats, most notably when she does her leaps.
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
Continuity mistake: The plane that the German is flying is an American plane, and there are obviously two different model of planes being used through the scene.
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
Visible crew/equipment: After Diana, who's wearing a nurses uniform, whispers to Steve that she'll be watching over him, when it cuts to Ashley Norman telling Wonder Woman about the booking and front page story, the shadow of the boom mic is moving on the wall at the right side of the screen.
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
Revealing mistake: When the elderly woman fires the submachine gun at Wonder Woman, the sparks created by her bracelets are bigger and brighter than usual, and we can see the wires under both of her arms to help create those special effects. We can even see the wires' shadows on the wall behind her.
The New Original Wonder Woman - S1-E1
Visible crew/equipment: To break the deadlock during the Tournament of Athletic Games, the last event is bullets and bracelets, and when Diana fires and hits her opponent, VIII, the wired remote that controls her bracelet sparks is visible in VIII's right hand.
The New Original Wonder Woman - S1-E1
Factual error: When Wonder Woman drops Steve off at the hospital, the nurse (a first lieutenant) is wearing her silver bar vertically on her collar. It should be horizontal.
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
Continuity mistake: When Wonder Woman and the Baroness are rolling down the grassy hill the Baroness is wearing open-heel stilettos with ankle straps, but when Wonder Woman throws her lasso the Baroness is wearing classic pumps.
Wonder Woman Meets Baroness Von Gunther - S1-E2
Continuity mistake: The ladder Tommy is standing on is coming loose from the wall it's attached to, and in the closeups we see the holes in the wall, but in the wideshots the wall is completely undamaged.
Wonder Woman Meets Baroness Von Gunther - S1-E2
Revealing mistake: After Wonder Woman saves Tommy from the falling ladder, when she uses her golden lasso to descend with Tommy (just a doll) we see her lasso (actually a thin rope) and its shadowy reflection on the windows, but we can also see the glistening of the stunt woman's safety cable as well.
Wonder Woman Meets Baroness Von Gunther - S1-E2
Visible crew/equipment: After Diana sees Tommy in trouble on the ladder she leaves Steve with the Baroness, and when she finds a private area by the lockers to transform into Wonder Woman, the reflections of four crew members are visible at the right side of the screen (widescreen version).
Wonder Woman Meets Baroness Von Gunther - S1-E2
Visible crew/equipment: When Arthur Deal shoots at Steve, just as Wonder Woman deflects the bullet, the remote that controls her bracelet sparks can be seen in her right hand at the bottom of the screen.
Wonder Woman Meets Baroness Von Gunther - S1-E2
Continuity mistake: When Wonder Woman calls the Dept of Motor Vehicles disguised as General Blankenship, the woman who answers the phone has long polished fingernails, but in the closeup of her going through the file box the fingernails we see are quite short and unpolished (looks like a man's hand).
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."
Wonder Woman Meets Baroness Von Gunther - S1-E2
Factual error: When Wonder Woman is running toward the burning Old Virginia Stables, she passes a modern 1970s era vehicle parked on the road.
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.
