Ms. Victor’s early career included a run as a singer and dancer at the Stardust Hotel in Las Vegas, according to IMDb. She went on to do more stage work internationally, including in Australia, Europe and Latin America. Ms. Victor later returned to Los Angeles and hosted the local talk show “Pacesetters,” a public affairs program. She also worked as a translator and interpreter at the 1984 Summer Olympics in Los Angeles, as well as for the BBC. In 1996, Ms. Victor starred in the short film “Libertad,” portraying a matriarch fighting to keep her fractured family together. The next year, she played the Hispanic translator in Robert Duvall’s “The Apostle.” She had roles in two other films with Mr. Duvall: “Assassination Tango” and “A Night in Old Mexico.” The director Frank Aragon said Ms. Victor was deft at balancing humor and drama in a way that “unleashes colorful, quirky personas that tickle the funny bone.” She also played the grandmother in the 2014 horror film “Paranormal Activity 5: The Marked Ones.” Her character was originally meant to die midway through the movie, according to Ms. Victor’s IMDb biography, but studio executives decided against that fate because “she’s too lovable and the audience won’t accept it.” She also had recurring roles on the shows “ER,” “Dead to Me” and “Snowpiercer.” In an interview in 2017 about her role in “Coco,” Ms. Victor said that the film would bring a broader awareness of Mexican culture to those who “don’t know enough” about it.
