The themes of Portillo centered around Latin American and Mexican stories, according to Variety. “Las Madres – The Mothers of the Plaza de Mayo,” earned Portillo an Oscar nomination.

“The Devil Never Sleeps” (1994) follow’s Portillo’s investigation of her uncle’s death in Mexico, the entertainment news website reported. In 2020, it was selected for preservation in the United States National Film Registry in the Library of Congress.

“Portillo’s works defy categorization, slipping easily between docu-fiction, experimental video, and the melodrama of telenovelas,” the Academy Museum’s interim director of film programs, K.J. Relth-Miller, said, according to Deadline.

Portillo was born on Nov. 11, 1943, in Chihuahua, Mexico, according to The Hollywood Reporter. She immigrated to Los Angeles with her parents and four siblings when she was 13.
