Early Hollywood was completely different than what it's become in the last 40 years. You have to understand it was an emerging industry back then with mostly an American audience. Actors had far more sway over their roles than the slaves they are today. For example, just look at how easy it was to get all of the cast for the Avengers to agree to their new TV show roles. Normally this was next to impossible to do and takes years of planning. But sure enough they churned it out like clockwork almost effortlessly.
