Most egregious example of "yellowface"

That guy at Jaded Lounge in Philly in the late 90s. You were MEXICAN!!!

Marlon Brando, "Teahouse of the August Moon."

Sidney Toler, Charlie Chan movies

Alec Guinness, "A Majority of One"

Fred Astaire & Lucille Bremer

Does that include the gowns?

Gale Sondergaard in The Letter (although I guess she was supposed to have been half Asian, not full, in the role). But it was a small role, good performance, and also the 1940s, so who really cares?

Ona Munson as Mother Gin-Sling in SHANGHAI GESTURE.

Featuring breathtaking Gene Tierney and slimy Victor Mature as a slimy Egyptian.

Definitely Mickey Rooney as he spoils an otherwise enjoyable movie.

Let's hear your definition of "egregious" first, OP, since it's one of those words that so often are misused by those feeling the need to apply it?

What about Alec Guinness in A Passage to India?

What color face was that?

Oh, I came on here thinking we were going to talk about Ariana Grande's turn at being Asian.

R8 It’s the same as “obscene”.

You know it when you see it.

(Not OP)

Look it up, r11.

Many of these are bad performances, but as awful as Luise Rainer is, I think she was trying to be sincere. Mickey Rooney feels like he’s actively trying to be offensive. That makes his performance the most egregious.

Shout-outs to the modern examples of white actors in Asian roles: Emma Stone in Aloha and Scarlett Johansson in Ghost in the Shell.

R13, you're so young and naive. Luise Rainer won an Oscar for that role!

Linda Hunt, The Year of Living Dangerously

Birgit Nilsson, Turandot

I'm with R13. Whatever we may feel about yellowface or other cross-racial performances, the ones in OP's list are basically well-intentioned -with the exception of Mickey Rooney's, which is so over-the-top it was bound to be offensive, even by 60s standards. The character of Charlie Chan may be stereotypical, but he is essentially a hero: brave, smart, kind, and with great integrity.

You picked Jerry Lewis for the photo/link but didn't choose it for the poll? Nice work, OP,

Rooney made me cringe when I first saw the movie back in the 60s. Those bits have never been funny. Blake Edwards taste level has always been questionable.
