Hollywood directors/producers/casting directors saying they can’t find the right actor for a role within the demographic called for in the script should be obvious to everyone as bullshit, but I don’t think people really understand exactly how bullshit it is.
When I was holding auditions for The N-Word, I did four days of auditions. I got over three hundred responses for three roles. I ended up auditioning around a hundred of them. This is for a non-paying low-budget webseries pilot. I found amazing actors for the roles. If I, with no casting experience or budget, can make that happen in two weekends, so can people with millions of dollars and months of time.
