Gilly, as you know, the film industry is multi-faceted and due to that, plus the facts of public demand and vested interests, it is not easy to find a position on this. However, it is my belief that we should forget where a film came from, who made it,etc. Is it good ? That is the only yardstick.
Also, please do note that a great many non American film makers are allowed a voice in the Hollywood film industry.
Who are the best film makers ? The people who make the best films of course, irrespective of race,creed or colour. As far as I am aware, nobody is these days banned from making films on the grounds of race,creed,ethnic origin or colour. Neither is anybody denied access to a public audience.
It,s high time we all just got on with things and stopped being obssessed with shouting foul where there is non. Either what you do is good enough or it isn,t. We,ve come a long way since the sixties,thank god, please lets not keep going back to the bad old days. Move on.
