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.
Factual error: In the opening sequence, a man placing dynamite on the truck is dressed in a camo-type uniform. This type of clothing was not introduced until 1981, and the episode was set in World War II.
Suggested correction: The camo type/color seen was around during WWII. It should also be pointed out the mistake claims it wasn't introduced until 1981, but the real life filming occurred in 1976. So they can't have been using camo type during filming that wouldn't even be introduced for another 5 years.
