Continuity mistake: While Nazis are invading Paradise Island, back at the deserted warehouse when one of the Nazis brings Drusilla a hot meal he slams the door shut, but when Drusilla hits him in the stomach the door is suddenly wide open, but when she rushes out of the room the door is closed and she pushes it open.

Audio problem: Hamlin Rule, the bad guy in this episode, is a singer. When he sings, his lips frequently don't match the words being sung.
Continuity mistake: When Steve lands his plane, all you can see in the background is what looks like a wide open desert. However, when he comes to a stop, the jet is now in the middle of a completely different background and there was not sufficient time for it to go from the desert to this location in such a short distance.
Judgment from Outer Space: Part 1 - S1-E10
Continuity mistake: When Wonder Woman is about to enter the spaceship, we see a close-up of Wonder Woman's lips because she whistles the tune that opens the ship's door.

This time, she's wearing lipstick, although she hasn't had time to put any on.

Continuity mistake: When Wonder Woman and the dog reach the cliff, the close-up shots show them against a blue backdrop that doesn't match the actual outdoor setting.
Continuity mistake: Diana is initially seen wearing a dark brown short-sleeved dress, but when she picks up the coffee, the dress inexplicably appears grey.
Answer: Yes, on the first episode of season 2, she is shown on the island, when another plane crash lands, she says, "They sound different from WW II".
