Lieutenant General
A lot of it is CGI. Spider-man just looks like he is CGI. Robert Downey Jr has talked about how unbearable it was being in the Iron Man suit but he's hardly in it. I think he's joking around. When you see him just standing with people in the scene, that's the only time he has to wear the suit. Anything else is CGI. He doesn't even have to do stunts or move around much while most of his other co-stars have to be there doing as many physical stunts as they can. And he gets paid the most. Lucky him.
