Marvel President Kevin Feige is a case study in paying your dues and rising the ranks, getting his start in the movie business as the assistant of X-Men producer Lauren Shuler Donner. From there he would become an associate producer on those movies before being tapped as the #2 for Marvel Studios and eventually President of Production, spearheading the Marvel Cinematic Universe as we know it. He remains in charge of it all, and as Captain America: The Winter Soldier star Frank Grillo put it, is seemingly the most powerful person in Hollywood, and to be honest it's hard to argue against it.
