UPDATED with Brosnan quotes: Beau St. Clair, who launched Irish DreamTime with Pierce Brosnan two decades ago and had been his producing partner ever since, died Saturday at her Malibu home after a 10-year battle with ovarian cancer. She was 63. Publicist Jennifer Allen confirmed the news to Deadline.

“Beau was the sister I never had, my dearest friend for 30 years,” Brosnan said today. “[She] was a beautiful woman in every way. She had style, grace, humor, intellect, and a kind heart that I will forever miss.”

Beau was the best.

Launched in 1996, Santa Monica-based Irish DreamTime produced 10 films, most starring Brosnan, including The Thomas Crown Affair (1999), The Nephew (1998), Evelyn (2002), Laws Of Attraction (2004), The Matador (2005), Shattered (2007), The Greatest (2009) and 2014’s Some Kind Of Beautiful and The November Man. The company’s next film is I.T., a thriller starring Brosnan, Anna Friel and Michael Nyqvist.

St. Clair has also led Irish DreamTime’s foray into television production. To date, the company has sold scripted series to Sony, Fox and Spike TV, according to her bio on the company’s website. Outside of Irish DreamTime, St. Clair produced John McTiernan’s MGM remake of Rollerball. Before forming the company, she worked on such films as The Mosquito Coast, Deception, Hideaway, Race the Sun, and The Edge. She has also worked on Broadway, acting as production supervisor on the musicals Threepenny Opera and Shogun.

“To be able to live the life of an actor,” Brosnan’s statement continued, “to make movies that touch people’s hearts is one of the greatest gifts any man or woman could wish for. I feel privileged to have worked alongside and collaborated with Beau Marie. Making films together was our dream come true. Beau Marie will be missed by all who were fortunate enough to know her.”
