The Girl from Ilandia - S2-E21
Character mistake: Wonder Woman warns Tina not to be trapped by a falling net on top of her. The problem is, Tina has missed her mark and is two metres away from the net, so she has to run and stand below the net to allow for the action scene to develop properly, which is absurd.
The Feminum Mystique: Part 2 - S1-E6
Visible crew/equipment: After the Nazis are defeated on Paradise Island, Queen Hippolyta tells her daughters that she has plans for those Nazis, and at the start of the next shot the set equipment's c-stand is visible at the left side of the screen (widescreen version).
Trivia: When Wonder Woman jumps over the fence, if you pause it for a split second, one can see the tip of a crew member's head. In the widescreen version, one can see the crew member and the lever he is pushing to allow for her jump.
Question: Does she go back to Paradise Island after WW2 in Season 1?
