So because it wont have corporate backing its going to be corny?
You need some "corny" business people behind things to tell you that its going to be good?
If you ask anyone to tell you a story about themselves they are going to tell you the way they remember it. We as humans only tell what makes us look good so that shouldn't be any different than any other of the bio pics that are done. After every biopic someone comes out and says they were not depicted accurately so him producing it or not producing it wouldn't change that. What we do get with him producing it is untold stories that we as outsiders were not there to see.
