@carolw That's the question. The comedian Sarah Silverman has raised the same issue; she referred to the practice of hiring non-Jews to play #Jews as "#Jewface".
Myself, I think acting is acting, and you aren't the person you're portraying, so why do you have to be just like them? That goes for races, ethnicities, gender, etc. There are lines, but finding them isn't as simple as asking if the actor is of the same lineage as the character.
That said: there's the question in the case of Bernstein of whether the nose is there to make Cooper resemble the great composer/conductor, or if it was added merely to signal his Jewish ethnicity. The latter would be a pretty solid (and quite literal) example of "Jewface".
I think there's a lot more complexity. Obviously we don't want to say that only Jews can play Jews ever. At the same time, when there are movements of awareness that go beyond physical description to ethnicity, or even things like sexual orientation, and then Jews are omitted, then we have to wonder why that is.
Sarah Silverman's point wasn't that Jews can only play Jews, but that Jews being omitted from the discussion was a form of antisemitism.
Yes I agree. It's about complexity. I am strongly opposed to rhetoric along the lines of "only X can play X". For example, here in the UK there has been magnificent colour-blind (and occasionally at least partly gender-blind) casting of Shakespeare.
But when a specific identity is central to a role, then it's often a problem if the actor doesn't share that identity.
And wearing a prosthetic nose to play a Jewish character? Um, just no.
@serge @carolw Yes, that's exactly it. The laughable and transparent non-troversy about Gal Gadot in the role of Cleopatra is a great example. Gadot was born and raised in the Middle East, where her family has lived for generations. Cleopatra was a descendant of Ptolemy, a Macedonian whose service to Alexander the Great led him to become the ruler of Egypt.
In other words: Cleopatra was about as Egyptian as I am. Modern Egyptians are largely of African descent, but Egyptians of her time were genetically closer to the Israelites. And yet, somehow Gal Gadot, a descendant of those Israelites, isn't "Egyptian" enough for the role. Hmmm.
As usual, #Jews are excluded from the panoply of ethnicities entitled to their own identity, just as they are uniquely denied the right to self-determination in their historical homeland.
Meanwhile, Bernstein's family have nothing but praise for Cooper and his portrayal of Lenny, so that's good enough for me.
