The crux of your argument is that Ridley Scott can't simply will the money to pay for a movie into existence due to his name and star power alone. This is false irregardless of whoever you are. Also the idea that having multiple colored leads, make your movie colored and targeting a colored audience. Is racist, and outdated. But also the model most studio execs subscribe too. Gina Prince-Bythewood did a wonderful interview with NPR that discuss these very themes I suggest you look it up. It basically boils down too that even if you are making a movie about a humanistic theme that someone of any race can experience, having a non-white cast will effect getting funding.
