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)
Character mistake: Arkon asks Storm to rule by his side as Empress. After she agrees, he introduces her to the crowd as Queen. (00:19:10 - 00:19:45)
Audio problem: When Jubilee says "But look, I think that Arkon guy really likes Storm," her mouth is completely closed for the words "I think that Arkon." (00:18:40)
Continuity mistake: In the wide shot of Arkon, Storm and the other X-Men approaching the crowd, Cyclops' face turns black. (00:18:10)
Continuity mistake: The character that says "We are saved" suddenly has gray-colored skin in the next shot. (00:18:00)
Audio problem: When Cyclops says "I hope they weren't from the Chamber of Commerce," his mouth is completely closed. (00:14:50)
Audio problem: When Jubilee says "I think," her lips are completely pressed together for the word "think." Saying "think" would require a person to touch their tongue to their teeth and lips apart. (00:13:15)
Continuity mistake: When the robot blasts Cyclops in the arm, you can see that his uniform tears. The tear has instantly mended itself in the next shot. (00:13:10)
Continuity mistake: When the X-Men are examining the orb in Beast's lab, the screen for the computer monitor has become shattered in one shot for no apparent reason. (00:08:55)
Continuity mistake: When Wolverine picks up the orb, the collar of Jubilee's shirt is yellow when it should be pink. (00:08:15)
Continuity mistake: When Storm throws her communicator and the portal-opening orb on the ground for the other X-Men to find, they land right next to each other. When Jubilee finds the communicator, the orb is missing until the shot changes. (00:06:40 - 00:08:10)
Audio problem: When Wolverine says "Now move over!", you can see his reflection in the truck's windshield and his mouth is completely closed. (00:07:00)
Audio problem: When Storm says "I command the Sahara Winds," her mouth is completely still for the last two words. (00:04:00)
Revealing mistake: In the opening shot of the Washington Monument, the monument is very noticeably shaking left and right as the camera pans up (likely indicating that the monument and the background are a composite image). (00:01:00)
Bloodlines - S5-E6
Continuity mistake: The yellow vertical line on the left side of Jubilee's shirt suddenly moves to the right side when she asks about Mystique's fate. (00:18:20)
Bloodlines - S5-E6
Factual error: When Rogue tricks the Friends of Humanity into firing on their own helicopters, two men are shown to be immediately parachuting from the helicopter at an altitude of at most, 100 feet. This wouldn't really be possible because jumping from such a low altitude would require the person to immediately deploy the parachute, which in this case would cause the parachute to be torn to shreds by the helicopter's rotor. If a person jumped from that altitude and deployed the parachute after free falling enough to clear the rotor, they would have fallen too far for the parachute to have been effective in allowing them to land safely, if the parachute even opened before they hit the ground. (00:16:30)
Bloodlines - S5-E6
Continuity mistake: The metal tubes on Wolverine's gloves disappear and reappear throughout the episode.
Bloodlines - S5-E6
Continuity mistake: When Graydon Creed is struggling with Nightcrawler, his tie falls out from behind his jacket. In the next shot, the tie is back in its original place. (00:11:30)
Chosen answer: It says MPO "First Exemplary Printing House" which is a real printing company in Russia founded by Ivan Dmitrievich Sytin in 1889. There seems to be something about "named after..." as well.
