When Constance Wu landed the part of Jessica Huang, the Chinese-American matriarch on the ABC sitcom “Fresh Off the Boat,” she didn’t realize just how significant the role would turn out to be. As she developed her part, Ms. Wu heard the same dismal fact repeated over and over again: It had been 20 years since a show featuring a predominantly Asian-American cast had aired on television. ABC’s previous offering, the 1994 Margaret Cho vehicle “All-American Girl,” was canceled after one season.

“I wasn’t really conscious of it until I booked the role,” Ms. Wu said. “I was focused on the task at hand, which was paying my rent.”

The show, which was just renewed for a third season, has granted Ms. Wu a steady job and a new perspective. “It changed me,” Ms. Wu said. After doing a lot of research, she shifted her focus “from self-interest to Asian-American interests.”

In the past year, Ms. Wu and a number of other Asian-American actors have emerged as fierce advocates for their own visibility — and frank critics of their industry. The issue has crystallized in a word — “whitewashing” — that calls out Hollywood for taking Asian roles and stories and filling them with white actors.

On Facebook, Ms. Wu ticked off a list of recent films guilty of the practice and said, “I could go on, and that’s a crying shame, y’all.” On Twitter, shebit back against Hollywood producers who believe their “lead must be white” and advised the creators of lily-white content to “CARE MORE.” Another tip: “An easy way to avoid tokenism? Have more than one” character of color, she tweeted in March. “Not so hard.”

It’s never been easy for an Asian-American actor to get work in Hollywood, let alone take a stand against the people who run the place. But the recent expansion of Asian-American roles on television has paradoxically ushered in a new generation of actors with just enough star power and job security to speak more freely about Hollywood’s larger failures.

And their heightened profile, along with an imaginative, on-the-ground social media army, has managed to push the issue of Asian-American representation — long relegated to the back burner — into the current heated debate about Hollywood’s monotone vision of the world.

“The harsh reality of being an actor is that it’s hard to make a living, and that puts actors of color in a very difficult position,” said Daniel Dae Kim, who stars in “Hawaii Five-0” on CBS and is currently appearing in “The King and I” on Broadway.

Mr. Kim has wielded his Twitter account to point to dire statistics andboost Asian-American creators. Last year, he posted a cheeky tribute to “the only Asian face” he could find in the entire “Lord of the Rings” series, a woman who “appears for a glorious three seconds.”

Other actors lending their voices include Kumail Nanjiani of “Silicon Valley,” Ming-Na Wen of “Agents of S.H.I.E.L.D.” and Aziz Ansari, who in his show, “Master of None,” plays an Indian-American actor trying to make his mark.

They join longtime actors and activists like BD Wong of “Gotham”; Margaret Cho, who has taken her tart comedic commentary to Twitter; andGeorge Takei, who has leveraged his “Star Trek” fame into a social media juggernaut.

“There’s an age-old stereotypical notion that Asian-American people don’t speak up,” Mr. Wong said. But “we’re really getting into people’s faces about it.”

This past year has proved to be a particularly fraught period for Asian-American representation in movies. Last May, Sony released “Aloha,” a film set in Hawaii that was packed with white actors, including the green-eyed, blond-haired Emma Stone as a quarter-Chinese, quarter-Native Hawaiian fighter pilot named Allison Ng.

In September, it was revealed that in the planned adaptation of the Japanese manga series Death Note, the hero, a boy with dark powers named Light Yagami, would be renamed simply Light and played by the white actor Nat Wolff. In “The Martian,” released in October, the white actress Mackenzie Davis stepped into the role of the NASA employee Mindy Park, who was conceived in the novel as Korean-American.

The list goes on. In December, set photographs from the coming “Absolutely Fabulous” film showed the Scottish actress Janette Tough dressed as an over-the-top Asian character. Last month, Marvel Studiosreleased a trailer for “Doctor Strange,” in which a character that had originated in comic books as a Tibetan monk was reimagined as a Celtic mystic played by Tilda Swinton.

And in the live-action American film adaptation of the manga series Ghost in the Shell, scheduled for next year, the lead character, Major Motoko Kusanagi, will be called Major and played by Scarlett Johansson in a black bob.

Studios say that their films are diverse. “Like other Marvel films, several characters in ‘Doctor Strange’ are significant departures from the source material, not limited by race, gender or ethnicity,” the Marvel Studios president Kevin Feige said in a statement. Ms. Swinton will play a character that was originally male, and Chiwetel Ejiofor a character that was originally white. Paramount and DreamWorks, the studios behind “Ghost in the Shell,” said that the film reflects “a diverse array of cultures and countries.”

But many Asian-American actors aren’t convinced. “It’s all so plainly outlandish,” Mr. Takei said. “It’s getting to the point where it’s almost laughable.”

The Academy Awards telecast in February added insult to injury. The show dwelled on the diversity complaints aired through #OscarsSoWhite, yet blithely mocked Asian-Americans with punch lines that banked on Asian stereotypes. The host, Chris Rock, brought three Asian-American children onstage to serve as a sight gag in a joke made at their expense.

“I have never seen the Asian-American community get so organized so quickly,” said Janet Yang, a producer who serves as a liaison between Hollywood and Chinese studios. She added, “It was the final straw.”

Within days, Ms. Yang and 24 other Academy members, including the actress Sandra Oh, the director Ang Lee and Mr. Takei, signed a letter to the academy taking it to task for the telecast’s offensive jokes. The academy’s terse reply only stoked the flames. Mr. Takei called it “a bland, corporate response.”

Online, even more Asian-American actors and activists have spoken out with raw, unapologetic anger.

Ms. Wen castigated “Ghost in the Shell,” tweeting about “whitewashing” and throwing in a dismissive emoji. Mr. Takei went off on “Doctor Strange” on his Facebook page: “Hollywood has been casting white actors in Asian roles for decades now, and we can’t keep pretending there isn’t something deeper at work here.”

Mr. Nanjiani jumped on Twitter to call out the red carpet photographer who told him, “Smile, you’re in America now.” (“I know when someone is racist, the fault is theirs and not yours,” he wrote. “But, in the moment, it makes you feel flattened, reduced and bullied.”) And Ms. Cho helped start a hashtag campaign, #whitewashedOUT.

“It’s intense,” Ms. Cho posted at the height of the action. “It’s that we have been invisible for so long we don’t even know what we can do.”

Meanwhile, television shows — competing for fresh content and audiences as the number of scripted series has increased dramatically in recent years — have helped expand the boundaries of what was once thought possible. Asian-Americans increasingly play leads and love interests and star in multiple family sitcoms.

Following “Fresh Off the Boat,” ABC debuted the sitcom “Dr. Ken,” featuring an Asian-American family led by the show’s creator, Ken Jeong, plus the drama “Quantico” starring the Bollywood actress Priyanka Chopra. On CW’s “Crazy Ex-Girlfriend,” Rachel Bloom, as the title character, pines after the hunky Vincent Rodriguez III, who is Filipino-American. They join such mold-breakers as Mindy Kaling, creator and star of “The Mindy Project,” and Lucy Liu, who plays a reimagined Dr. Watson in “Elementary.”

These shows help, but the issue is pervasive, including on TV. “The mainstream Hollywood thinking still seems to be that movies and stories about straight white people are universal, and that anyone else is more niche,” Mr. Ansari wrote in an email. “It’s just not true. I’ve been watching characters with middle-age white-guy problems since I was a small Indian boy.”

In films, a few roles have transcended stereotypes: Mr. Takei in the first “Star Trek” installments, Ms. Liu in the “Charlie’s Angels” features, andJohn Cho and Kal Penn in the stoner hit “Harold & Kumar Go to White Castle” and its sequels. And more are in development: a film adaptation of Kevin Kwan’s novel “Crazy Rich Asians” is underway, and the Vietnamese-American actress Kelly Marie Tran will play a major role in the next “Star Wars” installment.

But mostly, Asian-Americans are invisible. Though they make up 5.4 percent of the United States population, more than half of film, television and streaming properties feature zero named or speaking Asian characters, a February report from the Annenberg School for Communication and Journalism at the University of Southern California found. Only 1.4 percent of lead characters in a sample of studio films released in 2014 were Asian.

For Asian-American actors, the dearth of opportunities compounds itself. “An Asian person who is competing against white people, for an audience of white people, has to train for that opportunity like it’s the Olympics,” Ms. Wu said. “An incredibly talented Asian actor might be considered for a leading role maybe once or twice in a lifetime. That’s a highly pressured situation.”

So some are stepping behind the camera. In addition to actors creating their own shows, like Ms. Kaling, Mr. Jeong and Mr. Ansari, Mr. Kim of “Hawaii Five-0” has started his own production company, 3AD, “to help tell the stories of the underrepresented,” he said. Asian-American and other minority actors, he added, are “tired of waiting to be hired for the roles Hollywood creates for us.”

Audiences, too, are catching up. “There was a time when this conversation was completely foreign to people,” Mr. Wong said. Now young participants “are already fully versed in the issues and able to discuss them with great passion.”

Ellen Oh, a writer for young adults who devised the #whitewashedOUT hashtag, credited a generational shift. “For a long time, Asians have been defined by the immigrant experience, but now second- and third-generation Asian-Americans are finding their own voices,” Ms. Oh said.

They’re also employing a new vocabulary. “The term ‘whitewashing’ is new, and it’s extremely useful,” Mr. Wong said. In contrast to “yellowface,” which protested the practice of white actors using makeup and prosthetics to play Asians, “whitewashing” gives voice to the near-absence of prominent roles.

And the Internet has allowed people to imagine a parallel universe where Asian-Americans dominate the screen. Earlier this month, disappointed fans of the “Ghost in the Shell” franchise took a publicity still of Ms. Johansson in the lead role and Photoshopped in the face of Rinko Kikuchi, the Japanese star of “Pacific Rim.”

Recently the hashtag #StarringJohnCho went viral, reimagining the Korean-American star as the lead of rom-coms and action flicks. Though Mr. Cho has followed up the “Harold and Kumar” films with a role in the “Star Trek” franchise, he hasn’t been afforded the luminous leads offered to white actors with similar starts, like Seth Rogen after “Knocked Up” or Chris Pratt post-“Guardians of the Galaxy.”

“As I was Photoshopping John Cho’s face on top of Tom Cruise’s in the ‘Mission Impossible’ poster, my friends and I started chuckling a little bit, like, ‘How crazy would that be?’” said William Yu, the 25-year-old who created the hashtag. “Then I caught myself. Why should it be crazy?”

The campaign was followed by #StarringConstanceWu, which Photoshopped the actress into posters for films starring Emily Blunt, Drew Barrymore and, ahem, Emma Stone.

The activist outpouring is “a tidal wave,” said Keith Chow, the founder ofThe Nerds of Color, a website of geek culture criticism that has served as home base for several online campaigns.

It has swept up some members of white Hollywood in its wake. Ms. Stone has acknowledged that her “Aloha” role made her the “butt of many jokes.” And this month, the director of “Doctor Strange,” Scott Derrickson, tweeted, “Raw anger/hurt from Asian-Americans over Hollywood whitewashing, stereotyping & erasure of Asians in cinema. I am listening and learning.”

Whether that translates into change onscreen is an open question. “Everyone seems to be becoming slowly aware of how overwhelmingly white everything is,” Mr. Ansari said. “It’s almost like the whole system is slowly being shamed into diversity, but it’s moving at a snail’s pace.” He added: “Just look at the movie posters you see. It’s all white people.”(source:New York Times)
