Triumvirate of Terror! - S3-E8
Continuity mistake: When Joker zaps Wonder Woman and her mother, they are both standing in front of their thrones and fall forwards. But when Wonder Woman stands back up, her mother, still unconscious, is suddenly off to the side and behind the thrones. (00:11:35)
Iron Forged in Fire: Part One - S1-E1
Continuity mistake: After Tony says he is going to use the Iron Man armor to spy on Stane, he and Rhodey goof off some and wrestle. In the first shot of this, you see Rhodey’s arm come on camera and grab Tony’s, as Tony moves his hand up towards his own face. When he does, his arm and hand cast a shadow on his neck and chest. The shot cuts to a side view and suddenly the shadow has completely vanished. (00:15:00)
Continuity mistake: After the POV shot of Domino's sniper scope pulls up, a billboard with Magneto on it is on the right side of the screen, over a building with a red roof. When the shot changes, Domino is perched at the bottom left of the same billboard. If she was perched there, then the billboard could not have been to her right when she raised the sniper scope. Additionally, the roof of the building is now white. It's not a separate billboard on a different building either, because the waterfront and docks are the same angle respective to the first shot of the billboard and the shot of Domino loading the magazine into the gun. (00:18:19 - 00:18:42)
Continuity mistake: After Yoda cuts a hole in one of the droid battle vehicles, and throws the droid out, the following scene returns to Asajj and the Toydarian king. When their backs are shown, Asajj is standing close beside the king, but in the very next shot (showing them from the front), she is obviously a few feet farther from him. (00:17:08)
