Continuity mistake: The amount of bandages on Beast's torso vary depending on the shot. (00:14:35 - 00:19:45)
Audio problem: When Storm is saying "No, stop this madness! Cyclops, Logan..." her mouth is completely closed when she says "Cyclops." (00:16:55)
Continuity mistake: When Arkon states that Storm is the conqueror of his heart, he is holding up a goblet with his left hand and extending his right hand towards her. Not only is the bracelet on his right hand gold when it should be silver (the bracelet on his left hand remains silver in this shot), but his right hand looks rather effeminate. Arkon and Storm were sitting right next to each other and no one was shown to be standing between them in any other shot, so the right hand in question couldn't have belonged to another person. (00:16:40)
Audio problem: When Arkon says "As you wish, beloved," his mouth is slightly out of sync with the dialogue. (00:08:40)
Audio problem: Cyclops' mouth is completely closed when he says "Get your nose ready Logan." (00:07:20)
Continuity mistake: The banner with the picture of Storm and Arkon that the workers are hanging up appears to have a transparent background, but the underside is shown to be yellow. (00:07:00)
Continuity mistake: When Wolverine is talking about Storm being worshiped by a tribe when she was a child, the portion of his mask that runs down either side of his cheeks is yellow when it should be black. (00:06:45)
Audio problem: When Arkon says "We attack tonight," his mouth movement is slightly out of sync with the dialogue. (00:05:45)
Audio problem: When the bearded warrior says "They await only the order to strike," his mouth is completely closed. (00:04:40)
Audio problem: The sound of the slave shrieking in terror is recycled from previous episodes where Morph would make the same sound (for example the season 4 episode "Courage" and any of the five episodes he appeared in during season 2). (00:02:30)
Answer: Chris Potter, the original Gambit voice actor, did indeed quit the role in the 4th season. His last episode was The Phalanx Covenant Part 1 so it seems reasonable that Fox would limit the use of the character even though it was recast. It doesn't appear that Potter left the role due to animosity, he stated in an interview that he wished to play Gambit in the first live action X-Men film.
