PipingHotPiccolo said: "A fair distinction. Im not saying anyone SHOULD play any role, and i certainly think that trans actors should get all the opportunities they can. But Sarah Silverman has explored this a bit, how iconic Jewish characters are routinely played by non-Jewish performers (RBG, Leonard Bernstein, come to immediate mind). My view is the best performer should get the part, i could care less about their background, but i dont think thats particularly PC these days."
I don't have strong feelings on whether Fanny must be played by a Jewish actress, but I'd just like to expand on this because I love Sarah Silverman's podcast and generally find her world views very well-considered. Sarah always specifies that she fully supports "letting actors act" and that the individual portrayals of Jewish characters by non-Jewish actors (Scarlett Johansson in Jojo Rabbit, Rachel Brosnahan in Marvelous Mrs. Maisel, etc etc etc...) are not the problem, but rather, the problem is the trend of most Jewish roles going to non-Jews, especially, as she points out, if they're meant to be lovable, sympathetic, relatable -- whereas if they're the naggy girlfriend or the greedy business manager, it's much likely to go to a Jewish actress (see: Sarah Silverman in School of Rock and RENT).
