LOS ANGELES: TV’s “Fresh Off the Boat” creator Nahnatchka Khan was reveling in Oscar host Chris Rock’s deft comedic assault on white-fixated Hollywood. Then three Asian-American kids were brought onstage for a gag mocking them as ethnic stereotypes.

“It’s like going on a road trip with your fun friend, and halfway to Vegas he pulls over and shoots you in the leg,” Khan said, recalling her reaction to last weekend’s ceremony. “It was completely shocking and just so unnecessary.”

Rock’s skit ignited an outcry from Asian-Americans and others angered by its stereotyping and, more broadly, frustrated by how non-black minorities are portrayed — or ignored — by Hollywood, especially movie studios.

The response also has illuminated the gap between African-Americans, who have made some on-screen gains, and the lagging progress by other minorities, including Asian-American, Latinos and Native Americans.

Phil Yu, who observes Hollywood as part of his Angry Asian Man blog, said: “When I watch the Oscars as an Asian-American, I think, ‘It must be kind of nice to be disappointed that there were roles to be overlooked.’ I wonder what that feeling is like, because I can name no Asian-Americans that were in contention,” he said.

At least half of all TV or streamed projects from September 2014 to August 2015 and of the 2014 films studied lacked even one speaking or named Asian or Asian-American character, a study found.

But Rock’s attack on the industry’s diversity failures was fully black-centric, from one-liners to Black History Month skits. Then came the tuxedoed Asian-American kids, whom Rock presented as the “dedicated, accurate” accounting team that tallied Oscar votes, adding, “If anybody’s upset about that joke, just tweet about it on your phone, which was also made by these kids.”
