Formula 407 - S1-E12
Revealing mistake: After Major Keller leaves in the car with Steve and the formula, when Wonder Woman rushes in front of Maria to protect her when she's being shot at, the wired remote that controls her bracelet sparks is visible in her left hand, as she moves her arms to deflect the bullets.
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).
Formula 407 - S1-E12
Visible crew/equipment: While Lydia is being held at the shack, when Steve is with Professor Moreno he looks out the window at three Nazis on the street down below, and in the overhead shot of those three walking away from the car, their three T-marks are visible on the ground.
Formula 407 - S1-E12
Continuity mistake: After Diana sidesteps Antonio's advances, when Wonder Woman rushes off to save Steve she's grabbed by one of the Nazis who holds a chloroformed handkerchief to her face with his right hand, but in the closeup it's in his left hand, and then it's back in his right hand.
Judgment from Outer Space: Part 1 - S1-E10
Visible crew/equipment: When Wonder Woman shows up at the Library of Congress, in the overhead shot of her leaping over the bookcase, an unfinished part of the set is visible at the right side of the screen. Then after Andros has been taken from the Library of Congress, in the following shot at General Blankenship's office, we can see the end of the set wall at the right side of the screen (widescreen version).
Judgment from Outer Space: Part 1 - S1-E10
Visible crew/equipment: When Steve is telling Diana about the full scale search for Andros while they're in Steve's office, just as Steve sits down the camera pans to the left and we can see the shadow of the boom mic moving at the top left corner of the screen, as well as the end of the set wall at the left side of the screen.
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.
Revealing mistake: When one of Wotan's fellow Nazis in the rubber boat starts shooting toward Steve, in the closeup of Wonder Woman deflecting the bullets, one of the wired remotes that control her bracelets' sparks can be seen in her right hand, and as she starts walking toward the camera we can also see the other remote in her left hand.
Visible crew/equipment: After Wotan arrives on the beach Wonder Woman sees the other Nazi with a gun, so when she leaps into the air and lands in front of Steve we can see crew/equipment at the left side of the screen (widescreen version).
Continuity mistake: When Wotan and the other two Nazis arrive in the rubber boat, during the scuffle Steve is wearing boots, but his stunt double is wearing completely different shoes.
Continuity mistake: When Steve and Diana are off the coast of Virginia, they share binoculars to watch for three men coming ashore in a rubber boat, and when Steve raises the binoculars to his eyes the lenses are either extremely cloudy or the lens caps are on (it reflects no light), but in the following shot when Steve lowers the binoculars the lenses are perfectly normal. Then when Steve hands Diana the binoculars the lenses are still normal, but in the following shot when Diana lowers them it's once again extremely cloudy or the lens caps are on.
Visible crew/equipment: When Hank kicks Steve down the basement stairs, in the following shots the shadow of the boom pole/mic is moving around on the wall, at the left side of the screen. Then after Steve picks the lock on the chain he opens the back door, and the shadow of the boom mic is moving at the top of the screen.
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.
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.
Continuity mistake: When Wonder Woman chases after Benson her boots are flat and then the heels appear. It happens again later, while The Falcon tries to reach Professor Warren.
Visible crew/equipment: When Diana and Steve meet with Dr. Barnes at the hospital, they stop in the corridor to discuss the guard's condition, and when they resume walking the actors' T-mark and two tape marks are visible on the floor, where they had been standing.
Wonder Woman vs Gargantua - S1-E7
Continuity mistake: After the Nazis capture Steigler, while they're at the oil refinery Gargantua is in a cage behind them, and when Erica blows the whistle the gorilla reaches through the bars and grabs a large cardboard cutout of Wonder Woman, which was leaning against the wall, but the problem is that in the previous shots that cardboard cutout was not there.
Wonder Woman vs Gargantua - S1-E7
Visible crew/equipment: When Erica and Hans pay a visit to Dr. Osmond, just as Erica walks into the lab and stops in front of Gargantua's cage, the tape mark is visible on the floor in front of her feet (fullscreen version).
Wonder Woman vs Gargantua - S1-E7
Visible crew/equipment: While Wonder Woman searches for Steigler at the deserted oil refinery the Nazis force Steigler to shout for help, then when they all hide and Wonder Woman breaks into the room, the actors' two tape marks are visible on the floor near Steigler.
Answer: Yes, on the first episode of season 2, she is shown on the island, when another plane crash lands, she says, "They sound different from WW II". Later in the same episode a woman gathers background information on Wonder Woman. The woman says, "From 1942 to 1945, she helped the Allies win the war."
