Iron Forged in Fire: Part One - S1-E1
Continuity mistake: When Tony says he has to stop the train from hitting the building’s power generators, the camera zooms in on a train car at the entrance of Stark Tower by the tracks that has the generators on it, and there are two Stark International employees standing on the balcony beside it dressed fully in white. Only a couple seconds later, Tony flies down there to cut off the train, and suddenly the two guys have vanished. (00:18:00)
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)
Continuity mistake: When Wolverine is taking cover from the Sentinel Prowler, there is a blast mark in the pillar by his head. After Gambit asks Wolverine to give him back the collar, the blast mark has disappeared. (00:20:55)
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)
