Continuity mistake: Quite a few of the exterior shots of the jet which Steve is on are flipped shots (including the landing closeup), note the tail number "N207L" is backwards.
Formula 407 - S1-E12
Other mistake: At the start, the episode's textbox reads, "Fort Frazier Ordnance Testing Facility" with correct spelling, but in the next shot the base's sign reads, "Fort Frazier Ordinance Testing Facility" when it should actually be "Ordnance."
Revealing mistake: When Wonder Woman (Diana) uses her bracelets to dodge bullets, the many sparks that the bracelets emit, as the bullets hit, are controlled by wired remotes held in Lynda Carter's hands. They are quite visible in her fists in many episodes. Small red bits around the circumference of the bracelets also appear, which provide the flashing spark special effects.

Continuity mistake: When Diana comes home and spins into Wonder Woman there's a plant on the table under the mirror, but when she walks out of the kitchen with Drusilla that plant is on the floor.

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 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.
Wonder Woman Meets Baroness Von Gunther - S1-E2
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).
Continuity mistake: When Wonder Woman lassos the two hoods who were after Steve, in the wideshot the lasso's small loop is at the left encircling the two men, but in the closeup the small loop is at the right side, then it's back at the left.

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.

Wonder Woman vs Gargantua - S1-E7
Revealing mistake: While the circus crowd is gathered around the cage with Gargantua, there's a closeup of the gorilla as he roars and we can see the stuntman's human teeth behind the gorilla's teeth. It happens again in Gargantua's closeup while he's climbing up to Steigler's window.
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.
