Corrected entry: During the scene where Pepper is replacing Stark's heart device, his breathing in the computer-generated chest area is different from the rest of his (real) chest area. The computer-generated chest area looks rather fake, especially when his real chest is shown a few minutes later.

Correction: As has already been noted in the previous submission that was corrected, there is no computer-generated chest area. Robert Downey, Jr. wore a prosthetic on his real chest. The only thing that is faked is the illusion of a "hole." The rest of it is real.
