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."

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).

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).
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.
