I recently saw someone point out that it wasn’t Marvel Studios that fired Gunn, nor was it Walt Disney Pictures, the parent company of Marvel Studios. It was the Walt Disney Company, which is the parent company of Walt Disney Pictures.
If it was either of the first two, I’d say Gunn had a shot at reinstatement, but it being the uppermost level of Disney’s corporate structure makes me thing it’s all but impossible.
I’d really love to hear Feige weigh in on the situation, but I’m being he’ll keep his mouth shut about it for a long time.
