Continuity mistake: When Red Skull is leaving Wolverine and Captain America alone, he sets Captain America's shield on a table and Wolverine is shown to be hanging from stocks by his wrists with Captain America on his left and the table on his right at roughly a 45 degree angle. In a wide shot after Red Skull has left the room, the shield has vanished from the table and Wolverine is now several feet from where he originally was, with Captain America roughly at his 12 o'clock and the table roughly at his 3 o'clock.
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.
