LOS ANGELES — After black actors and films that focused on black characters were overlooked for Oscar nominations in 2015 and 2016, the #OscarsSoWhite social media outcry was so fierce that Hollywood was forced to listen. The Academy of Motion Picture Arts and Sciences began a determined diversification effort, and last year there were six black acting nominees, a record.

Whitewashing, or casting white actors as nonwhite characters, has galvanized Asian-Americans in Hollywood. Stars like Constance Wu have railed against the practice, hurting ticket sales for films like “Ghost in the Shell,” a Japanese manga adaptation starring Scarlett Johansson.

But as Hollywood tries to deal with those issues, not to mention the fallout from the harassment crisis that began with Harvey Weinstein’s downfall, the minority group that Hollywood excludes the most onscreen — Latinos — is trying to create its own bullhorn moment.

“We are expecting that we are going to have to go to the Academy Awards this year and demonstrate,” said Alex Nogales, president of the National Hispanic Media Coalition, a watchdog organization. “We’ve tried to push in less hostile ways. But these studios don’t seem to understand anything else.”
