According to Cruz, the incident happened on the day she was preparing to film a nighttime musical scene for La Bola Negra. While she was getting ready in hair and makeup, a doctor called about the results of a recent medical scan and warned that it appeared she might have a brain aneurysm.
The news was devastating. Cruz said she immediately started crying but was told by the doctor that she could continue working for the moment.
The timing made the moment even more surreal: the scene about to be filmed required her to sing and dance with hundreds of extras. Despite fearing for her life, she went ahead with the performance.
Cruz later recalled that during the shoot she kept thinking, “I may die.”
Rather than halt production, Cruz completed the musical number as planned. She described the experience as emotionally overwhelming—performing in a highly choreographed scene while privately processing the possibility of a serious medical condition.
Only later, after undergoing additional medical examinations, did doctors determine that the earlier concern was incorrect. The suspected aneurysm was not present, confirming that the frightening diagnosis had been a mistake.
Despite the tense memory behind the shoot, La Bola Negra has been warmly received on the festival circuit. The film—directed by Javier Calvo and Javier Ambrossi, widely known as Los Javis—premiered at Cannes and reportedly received a 20‑minute standing ovation, one of the longest responses at the 2026 festival.
The Spanish-language film draws inspiration from the work of Federico García Lorca and explores the lives of interconnected gay men across different stories and eras.
With its emotional themes and ambitious production, the movie is competing in the festival’s main lineup for the Palme d’Or, Cannes’ highest prize.
For Cruz, the story behind the film’s production has become inseparable from the movie itself. What began as a terrifying phone call turned into a reminder of the unpredictability of life—and the strange realities of filmmaking, where a performer may be expected to deliver a joyful musical performance while privately confronting the possibility of a life‑threatening diagnosis.
In the end, the medical scare passed, the scene was completed, and the film went on to receive one of the festival’s most enthusiastic receptions.
For Cruz, that night on set remains unforgettable—not just for the performance, but for the fear she carried while delivering it.
