Revealing mistake: When the scientist melts and collapses on the table, the wires controlling the dummy are visible.
Continuity mistake: Wonder Woman throws her boomerang tiara, which falls down half a metre ahead. The shot changes and it's now flying up in the air for over 10 metres.
Continuity mistake: When Wonder Woman spins around and transforms herself, the sunlight swaps from dark to bright.
Continuity mistake: Inside the vault, when Diana spins into Wonder Woman, there's a golden picture frame on the left. When she has changed, the frame is gone.
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.
Revealing mistake: The underwater scenes of Wonder Woman are supposed to take place in the ocean, but it's very obviously a swimming pool with drain holes and a light niche.
Continuity mistake: Diana spins herself into Wonder Woman before she enters the gym. Watch the trash can behind her - it suddenly disappears. Additionally, in the widescreen version, a security guard can be seen standing between the car and metal door, though surely Diana would not transform into Wonder Woman right in front of someone; she even looks around to be certain nobody is watching her (the guard is not visible in the original fullscreen version).

Visible crew/equipment: After Wonder Woman rescues Nadia's boyfriend by catching and tossing the two baddies, a woman wearing green and a man wearing brown, off screen, you can see something suddenly emerge and disappear at the doorway, directly behind Wonder Woman, as she's grabbing the toaster's cord to go and tie up the two baddies together.

Continuity mistake: When Mariposa is skydiving out of the plane, any time he's seen from afar, he's wearing a black oxygen mask. When the camera is closer to Mariposa, he's not wearing a mask. However, when he lands, he is wearing a mask.
Visible crew/equipment: After Bo and Lois Taggert are captured, Wonder Woman runs back in the room to grab a cable. Then a white object briefly appears on the right. Bo and Lois were not wearing white, so it's either a piece of filming equipment or a crew member's arm.
Revealing mistake: When Bo and Lois Taggert are tossed by Wonder Woman, check the floor and you'll see their shadows bouncing on a rectangular shadow, which is obviously the crash mat.
Visible crew/equipment: In the gym, when Wonder Woman jumps on the trampoline, a crew member's arm is visible on the right side of the screen.
Revealing mistake: When the helicopter transports the phone booth, the man inside has been replaced with a stiff, unrealistic dummy.

Revealing mistake: When Wonder Woman tries to stop a car, skid marks from previous takes are already on the road. (00:23:22)
Continuity mistake: Wonder Woman jumps through a window, and all of the glass smashes out, everywhere. In following shots there is no glass on the floor or the surrounding area.
Continuity mistake: When the bad guy brings the suitcase to the control room, the time on the timer behind him jumps forward and backwards between shots; no continuity. (00:05:30)
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.
