I've been following the debate at the website of the world's oldest Jewish newspaper, The Jewish Chronicle (thejc.com). Some of their opinion writers are against the practice and call it acting in "Jew-face" (a reference to the minstrel-age performers acting in "blackface") and others give it a big "Meh."
Speaking to the role of a Jewish gangster played by Gentile Tom Hardy in the TV Series "Peaky Blinders," one OpEd author wrote,
"...I defy you to find any other actor, let alone a Jewish actor, who could bring even a fraction of what Tom Hardy does to the role. So here we have an explicitly and crucially Jewish role which needs to be played by a non-Jewish actor.
And if that doesn’t destroy the idea that we should always try casting along racial, religious, national or whatever grounds, I don’t know that will...."

Thats probably closer to what he looked like than if you had a Han actor or something playing the part. The little chinese man on a pony is a modern fiction.
