Remember when Tobey Maguire was cast to play Spider-Man back in 2002, and everyone thought he didn't look pumped up enough to play our favourite wall crawler? Well to keep fan-boys from going crazy about this casting choice, Tobey proved everyone wrong by buffing up. Check out the scene of him standing in front of the mirror, admiring his toned physique.
However, I'm pretty sure all of us know that when it came time to donning the Spider-Man costume, Tobey was probably not in it all the time (except those times when he's unmaksed). For the rest of the scenes with Spider-Man, I'm pretty sure they used stunt doubles. Now I don't have an issue with stunt doubles. They professionals, and I'm sure the director wouldn't want the actor to get hurt for nothing.
However, I draw the line when they start to use stunt doubles that don't share the same physique as Tobey. When you see Spider-Man and he looks taller or has body shape that is different from the actor playing Peter Parker, it really draws me out of the movie.
