The Pitt star Isa Briones has issued a strong message to fans who have taken to shouting references to the medical drama at her while she is on stage in a Broadway musical.

Briones, who is performing in the musical Just in Time, has rapidly risen to fame for her role in the hit HBO show, as resident doctor Trinity Santos. In the second season of the show, which premiered in January, Santos repeatedly struggles with finishing her charting during her shift.

“Hey, hey, hey!” Briones wrote on Instagram. “Once again, Broadway is not a circus. Do not yell whatever you want at the performers. Yelling ‘when are you going to finish your charts’ before I sing Who’s Sorry Now? is fucking disrespectful to the performers onstage and your fellow audience members. Y’all are pissin’ me off.”

She added: “Love and light and please remember you are occupying shared spaces and watching art.”

Briones made her Broadway debut in 2024 as Eurydice in Hadestown. In April she began playing Connie Francis in Just in Time, a jukebox musical about the US singer-songwriter Bobby Darin.

Since it premiered in 2025, The Pitt has become hugely popular around the world and transformed the careers of many of the young actors who play residents and student doctors working in the fictional Pittsburgh Trauma Medical Center.

Briones’ co-star Patrick Ball, who plays Dr Frank Langdon, is also performing on Broadway and has spoken about Pitt fans waiting outside the stage door with gifts, telling the Prestige Junkie podcast: “When you’re making TV, we live in our little fluorescent box on the Warner Brothers lot – we’re sort of removed from the people who are actually receiving our work. Then you walk out of the stage door, and everybody who has become so supportive of The Pitt, they’re all there. It’s been such a blessing.”

Since the second season began in January, The Pitt has topped Nielsen’s streaming charts with more than 1bn minutes of watch time for eight straight weeks.

The second season is expected to dominate the Emmys in September. The first season was nominated for 13 Emmys and won five, including best drama series, best actor for Noah Wyle and best supporting actress for Katherine LaNasa. A third season is in the works.
