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
Revealing mistake: When one of the Nazis brings Drusilla a hot meal while she's being held in the deserted warehouse, in the shot just as she whacks him in the stomach we can see the stunt cable over the Nazi (stunt double) which lifts and pulls him back.
Wonder Woman vs Gargantua - S1-E7
Continuity mistake: When Wonder Woman arrives at the warehouse where Steigler is being held, as she's using her lasso to scale the building the high heels on her boots have vanished, and they're now flats.

Continuity mistake: Diana spins around inside the boat, but when she transforms into Wonder Woman, she's inside a white room. Then she keeps spinning into her wetsuit, and she's now back in the boat.

Continuity mistake: When the building collapses, shot changes to show a different angle, and it's now a totally different building (check its colour, number and shape of the windows and the railing on the rooftop, among many others).

The Man Who Wouldn't Tell - S2-E20
Deliberate mistake: In order to knock down Ted at the laundry place, Diana opens a bag filled with clothes that are supposed to fall on him. The bag is too low plus the actor is away from the bag, so when she opens the bag he crouches, then grabs the clothes and pours them on top of him and falls down. It's all very lame.
The Girl from Ilandia - S2-E21
Revealing mistake: When Tina jumps out of the window, she is a young girl. When she runs away (and all further jumps and stunts in this episode), she is replaced by an adult, taller stunt.
The Girl from Ilandia - S2-E21
Revealing mistake: When Wonder Woman tosses balls at Tina for her to stop them mentally, the edge of the protective glass in front of the girl is visible, plus there is a yellowish reflection that wobbles every time the ball hits the glass.

Visible crew/equipment: Crew members holding a boom mic pole are reflected on the side of the car.
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.
