"I believe that is true. Hamilton casting director got in trouble for specifying that they were only seeing 'non-white actors' for most of the roles. They eventually had to change the casting notice to say that they would see all ethnicities even though they obviously won’t cast a white actor to play George Washington."
Right, I had heard that. So I was surprised that it was stated ahead of time in the press item that the the role of Hercules was going to be cast with an African-American actor (or a black actor, I don't remember the exact phrasing). But maybe the actual casting notice was worded differently.
