I think if you put Denzel in this same situation, he'd continue to get some work because he was an established A-List actor for decades going in, but he'd get treated worse than Depp.breh... being white trumps being an A lister. This is America.
I think once you reach that level all they care about is money when it comes to the movies, it will be interesting to me to see how much $$$ depp's first big movie makes after all of his scandals because there is definitely a loud audience that hate him forever despite what came out in court, but studios have still courted him, even Disney wanted him back.
