But Ken Jeong? The guy whose biggest movie role to date is "Mr. Chow" in The Hangover, where he pranced about in tighty whities with an exaggerated Chinese accent and making slow jerkoff motions?
It's hard to perceive much of his work as anything but modern variations of Long Duk Dong, ultimately I consider his work to have added to Asian stereotypes.
The guy is free to take the role he wants, but IMO as far as "actors dismantling Asian stereotypes with their work" his career so far has been as far from it as it gets.
Also the weird history of Asian actors playing Native Americans in Westerns...
