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.
Revealing mistake: In every shot of Wonder Woman's plane flying, it's very obvious that whoever is inside has been replaced with a blatant doll.

Revealing mistake: When the elderly woman fires the submachine gun at Wonder Woman, the sparks created by her bracelets are bigger and brighter than usual, and we can see the wires under both of her arms to help create those special effects.

Visible crew/equipment: To break the deadlock during the Tournament of Athletic Games, the last event is bullets and bracelets, and when Diana fires and hits her opponent, VIII, the wired remote that controls her bracelet sparks is visible in VIII's right hand.

Other mistake: Watch when Diana is looking at the newspaper. The headline reads "Steve Trevor Recovering Well, Now Able to Speak", but the story is something about a US Envoy and has nothing at all to do with Steve Trevor.
The New Original Wonder Woman - S1-E1
Other mistake: After Von Blasko has given Drangel his orders Von Blasko wishes him "good hunting," and when it cuts to the shot of the aircraft taking off, we see the backwards number "5" revealing it's a flipped shot.

Wonder Woman Meets Baroness Von Gunther - S1-E2
