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.

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.

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.

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.

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).

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.

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).

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."

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.
