The Return of Wonder Woman - S2-E1
Revealing mistake: During the scenes on the jet with Steve and the others, before landing on Paradise Island and when the Amazon women are aboard, the end of the cabin and cockpit sets are visible at either the right or left side of the screen in some shots (widescreen version).
Revealing mistake: The wires holding the small satellite the two alien men are 'channeling' across the lake are visible although it's supposed to be floating.
