Karla Sofía Gascón of ‘Emilia Pérez’ Could Make Oscar History

There has never been a movie quite like “Emilia Pérez,” so it’s fitting that its star Karla Sofía Gascón is one of a kind, too.

In the film from the director Jacques Audiard, Gascón plays a Mexico City cartel kingpin who fakes death in order to transition abroad in secret. Years after her gender-affirming surgery, the newly rechristened Emilia contacts the lawyer who helped arrange it (Zoe Saldaña) and has one more request: a reunion with the unsuspecting wife (Selena Gomez) and children she left behind, even though returning to the scene of her old crimes could have dire consequences.

The multitude of genres suggested by this synopsis — a gritty drug-world exposé, a family melodrama, a trans-empowerment narrative — are further complicated by the fact that “Emilia Pérez” is a musical, meaning the characters are liable to break into song whether they’re in a love scene or clashing in a heated gunfight. In a film full of big swings, it’s hard to imagine any of the wild ideas holding together if it weren’t for Gascón, who can contain all of those multitudes in a single freighted look. Many pundits believe that after Netflix releases “Emilia Pérez” in November, Gascón will make history as the first openly trans actress nominated for an Oscar.

In May, the 52-year-old Gascón was the breakout star of the Cannes Film Festival, where “Emilia Pérez” won a best actress award that was shared among all of the movie’s leading women. Since her castmates had returned home before the awards ceremony, an overcome Gascón took the stage on their behalf, and her emotional speech was the night’s highlight. At the microphone for nearly six minutes, Gascón flitted between Spanish and English as she tearfully asserted the humanity of trans people, joked about bribing the jurors, paid romantic tribute to her co-star Gomez, then apologized to Gomez’s boyfriend for her ardor.

Afterward, Gascón tried to explain her speech’s breathless sprawl. “I’ve never been given a prize,” she told reporters. “I’ve mostly been given blows and kicks.”

Spanish-speaking audiences may already be familiar with Gascón, a veteran of Mexican telenovelas who starred in the hit 2013 film “Nosotros los Nobles” and transitioned six years ago while in the public eye. “It was very difficult,” she told me recently over lunch in Los Angeles. “People knew me a certain way and then I changed, so I constantly felt that I had to justify myself. I was always fighting with everyone.”
