Who is head of Marvel Studios?
Isaac Perlmutter
In September 2015, Perlmutter stopped overseeing the development of Marvel Studios. Disney felt the studio head, Kevin Feige, should report directly to the chairman of The Walt Disney Studios, Alan Horn, so all cinematic properties of Disney, including Pixar and Lucasfilm, were under one management structure. The restructuring was allegedly due to Feige's "frustration" of working with Perlmutter as well as some alleged controversial comments and actions by Perlmutter, such as replacing the casting of Terrence Howard as James Rhodes with Don Cheadle because black people "look the same." A person with knowledge of his creative approach said, "Ike Perlmutter neither discriminates nor cares about diversity, he just cares about what he thinks will make money." 
Jeph Loeb, who oversees Marvel Television and the television properties of the Marvel Cinematic Universe, still reports to Perlmutter.
Disney Consumer Products and Interactive Media
In 2009, Disney acquired Marvel Entertainment for $4.24 billion. Josh Silverman, a senior executive at Marvel, was appointed Executive Vice President of Global Licensing for Disney Consumer Products and helped facilitate the Disney-Marvel integration. In 2011, Disney fired Marvel Studios' marketing department, taking over marketing of their films beginning with the 2012 film "The Avengers".
