The Sicario/Arrival director’s sequel to Blade Runner, which was set in an Asian-overrun Los Angeles in 2019, looks like La La Land the Sci-Fi Movie: in the future, apparently, white people will still make up most of the cinematically interesting Angelenos.
Judging by the IMDB cast list, Edward James Olmos will be the only Chicano left in Los Angeles.
By the way, Olmos’ police detective in Blade Runner was likely inspired by the Mexican-American police detective in Raymond Chandler’s 1952 novel The Long Goodbye. Olmos then went on to play the mournful Lt. Castillo in Miami Vice. (The TV show wasn’t really in gear until he was added midway through the first season.) The unhappy Mexican detective also shows up in Larry Gelbart’s fine Broadway musical tribute to L.A. noir, City of Angels. If you are going to write a spec script, think about writing a noir one, in part because it’s kind of okay to borrow stuff from the hard boiled masters, as we can see from how even a minor character from The Long Goodbye has had a terrific afterlife in a fine movie, TV show, and musical.
