What I will say is that Creed is what got Feige to give Coogler the control he wants. I read somewhere that it was Kevin Feige's favorite film of 2015. However, before that Coogler wasn't Marvel's #1 choice. Ava and then Straight Outta Compton's F. Gary Gray were ahead of Coogler. They both passed on it. Feige saw Creed and said fukk it and gave him more control than normal imo. Knew that by letting him bring in his own people.
So it worked out. If Ava or F. Gary Gray signed on Marvel might have tried to be more controlling. Creed won them over so much that they got a great director and ended up giving him more control.
I wonder why F.Gary Gray passed.
There was also talk of the Director from Dope being in early talks as well huI that might have just been rumor
