Oh, and Ansel Elgorts father is Jewish, though I dont know how Ansel was raised. Robert Downey, Jr., Sean Penn, and Ed Skrein were also born to Jewish fathers and non-Jewish mothers. Armie Hammer, Chris Pine, Emily Ratajkowski, Mark-Paul Gosselaar are part Jewish.
Actors with one Jewish-born parent and one parent who converted to Judaism: Dianna Agron, Sara Paxton (whose father converted, not her mother), Alicia Silverstone, Jamie-Lynn Sigler.
BTW, did you know that Timothe Chalamet is Jewish? His mother, who is American, is Jewish.
I mention this because the mainstream media is pathologically obsessed with exactly only one half of his background, French, and categorically refuses to mention his other half, Jewish. Even though his character in this movie isn't French - he's Jewish, and spends half the movie wearing a Star of David.
So if not now, when? In fact, Call Me By Your Name is the rare major film where three actors of Jewish heritage (Chalamet, Hammer, Stuhlbarg), play Jewish characters in the leads.
