Revealing mistake: After Howard’s death, Tony and Rhodey are trying to get back into Stark International. A guard is giving them a hard time and he is wearing some sort of shades and head piece. When it cuts to a close up of his face as he talks to the people inside, on the left side of his glasses near where it meets his hair, there is a texture glitch in the animation. The glass in one spot is flickering around like TV static. (00:07:10)
Revealing mistake: When Grievous falls to the ground as the Gungans throw plasma balls at him, the lance General Tarpals stuck through his torso blatantly clips through the ground. (00:15:03)
