Maybe if there was some good films made by blacks or had black actors. Several films that had white leading actors were replaced by black actors totally bombed. Let’s see a remake of Gone With The Wind starring a black actor and see how it does or any big name film. Rear Window, From Whom The Bell Tolls, Citizen Kane (starring Morgan Freeman?) Here you go - Casablanca. The list goes on.
Wouldn't you need to rename it "Casanegra"?
