Isabelle Thomas, British documentary filmmaker and the wife of Oscar-nominated Killers of the Flower Moon producer Bradley Thomas, was found dead at a Los Angeles hotel this week, medical records show. Thomas was 39.

Isabelle Thomas died by suicide and was discovered with “multiple traumatic injuries” at a local hotel, according to online records from the Los Angeles County Medical Examiner’s Office. Citing law enforcement sources, TMZ reported this week that on Monday, Thomas had lept from a high-up floor at the Hotel Angeleno; the 17-floor Westwood hotel is notable for the balconies that wrap around the building on each floor.

Police sources reportedly indicated that she was discovered dead at the scene when first responders arrived.

“Isabelle was the light of our lives,” said the family in a statement to the L.A. Times. “She was courageous and took all life’s opportunities without fear, showering love and kindness on her friends, family, and children along the way. Her projects were as diverse as her passions, reflecting a curiosity about people and our culture that inspired everyone lucky enough to spend time with her. We remember her as a soulmate, beautiful daughter, sister, devoted mother and wife.”

The British producer, also known as “Izzy,” is from the Cotswolds in the U.K and resided in California with her husband and their two children. According to her website, she graduated from Oxford University and went on to advise on projects for international entertainment companies, private family offices, global membership spaces, start-ups, the UN and The World Bank. 

Isabelle married Bradley Thomas, a producer of major films for decades, in 2018. The couple was spotted at red carpet events around town while his career flourished as a producer on Clint Eastwood’s The Mule in 2018 and 2022’s Palme d’Or-winning satire Triangle of Sadness. The two were photographed together as recently as Jan. 13 at the 2024 BAFTA Tea Party at The Maybourne Beverly Hills.

Isabelle Thomas’ death comes as her husband is in the height of award season as he promotes Killers, which, alongside fellow producers Dan Friedkin, Bradley Thomas, Martin Scorsese and Daniel Lupi, is up for the 2024 Oscars best picture trophy.

Bradley Thomas’ producing career began with the Farrelly brothers’ hit 1994 comedy Dumb and Dumber and has not lost momentum over 30 years. He produced several of the duo’s subsequent comedies, including There’s Something About Mary and Shallow Hal, then later teamed up with legendary filmmaker Ridley Scott for All the Money in the World and Swedish filmmaker Ruben Östlund as EP on the biting satires that followed his debut, Force Majure.
