Iron Forged in Fire: Part One - S1-E1
Continuity mistake: As Rhodey and Tony are walking by a building, Rhodey tells Tony to not worry, as in two years he can fire Stane. The first view shows their shadows directly under them, like the sun is at its zenith. It then cuts to a shot from above their heads and now their shadows are elongated and cast on the wall beside them. (00:09:35)
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 Shadowcat tells Iceman that Emma Frost knows what he is thinking, the shocked expression on his face is drastically more pronounced when the shot changes. (00:05:37)
Continuity mistake: When Ahsoka asks R3-S6 how the droid's first adventure was and Anakin snaps that he thinks he's lucky to be alive, Anakin's clothes below his belt are missing the black overtunic, leaving only the red tunic below it. (00:20:17)
