Update: A second report states the blame lies with the handling of Captain America: Civil War.
Some new details/rumors surrounding the ouster of of Marvel CEO Ike Perlmutter and his Marvel Comics creative committee have come to light that state the reason for the dismissal was the failure of Avengers: Age Of Ultron.
Quick recap: Marvel Studios president and producer Kevin Feige has moved Marvel Studios away from Perlmutter and the comics and TV divisions of Marvel, and more into the Disney fold, which also saw the end of the Marvel Creative Committee (Quesada, Bendis, Buckley).
It’s said Feige used the “failure” of Avengers 2 as leverage to get rid of Perlmutter and the Creative Committee, which according to the report, was disbanded a few months ago (and may signal they are not as involved with Captain America: Civil War and Doctor Strange).
My two cents regarding Avengers 2 being a “failure,” I would have to agree as I was really disappointed with the movie. I wasn’t a big fan of how they portrayed Ultron, and I also felt they didn’t give Whedon a lot of creative freedom (as a lot of his stuff was cut). I can recall an interview with Whedon from a while back where it sounded as if Avengers: Age Of Ultron would be an Empire Strikes Back; however, I think we can all agree, Avengers 2 can’t even compare. Whedon said he was going to “twist the knife” and “dig a little deeper” with the sequel, which I don’t think the movie came close to doing at all.
