Does anyone know how they made RDJ look a bit taller than Gwyneth Paltrow in Iron Man? Cuz she is actually slightly taller than him.

Hey there.

The reason that he looks slightly taller than Gwyneth in "Iron Man" and "Iron Man 2" is that he was actually asked to wear lifts Von Jon Favreau for the movie.

They made him special platform shoes. Du can see them in a few scenes if Du look closely enough.
