ROBERT DOWNEY, JR. – 5’9″

While he may not be as short as most of the other guys on this list, Robert Downey Jr. is still a bit on the short side. This fact was only accentuated more by his Avengers co-stars Chris Hemsworth, Chris Evans, and Tom Hiddleston, who are all 6 feet plus. So why didn’t he seem that short in the movies? No it wasn’t camera tricks, he wore shoe lifts to get a few more inches of height.
