Technically they couldn't complain about this. Obamas mom is as white as mine, the black father abandoned the family when Obama was a baby. He was raised in Hawaii by a white mother and with help from the white grand parents and went to a white school, and then went to Harvard to become a lawyer. There is not a shred of blackness about him. Ryan Gossling, as well as any white man, could play Obama perfectly and without any research. The only trouble would be when they ask the actor to start fucking a transexual black man who plays Big Mike. That's where white male actors can't relate to the script any more.
