Continuity mistake: When Iron Man and War Machine are battling Titanium Man, they each grab one of his legs and flip him on his back, with the two shown to be standing near his feet afterwards. The shot then changes to show Iron Man jumping towards Titanium Man, even though he was already standing right by him. When the shot changes again, Iron Man is at Titanium Man's feet, but War Machine is nowhere to be seen.
Continuity mistake: When Mandarin, Modok and Justin Hammer are scanning the ship, they are closely surrounded by equipment. When the shot changes and Mandarin is telling Justin Hammer that he is not unpredictable, much of the equipment is gone and the area is more wide open.
Continuity mistake: When Tony and Rhodey are talking to Bill Clinton, the stripes on the knot of Clinton's tie, from left to right, are blue, red, blue, and red. It then changes to red, blue, red, and blue when Clinton is asking Tony about his satellite systems. (00:04:32 - 00:05:26)
Continuity mistake: When the MODOK E.L.F. is in the fish tank watching Rhodey at his computer, it is located at the bottom of the tank near the sidewall on its right. When the shot changes to over Rhodey's shoulder, the MODOK E.L.F. is now at the top-center area of the tank. (00:05:50)
Other mistake: When Tony and Julia and the two tailing reporters walk past the press, they appear out of thin air. They should have either appeared from the courthouse door, which is closed the entire time, or from the left side of the screen. Instead, they appear on screen from just behind the reporter in the foreground, who is not obscuring enough of the screen for Tony and Julia to have gone unseen up until that point. (00:10:03)
Continuity mistake: When Iron Man is stepping into his armor, he is wearing a blue shirt and a suit jacket. When the armor is shown closing around his torso, he is suddenly wearing some kind of body suit with what appears to be sensors or electrodes on it. (00:10:57)
