Film Career
Flanagan made her film debut in 1967, portraying Gerty MacDowell in Joseph Strick’s adaptation of James Joyce’s “Ulysses.” She followed with a role in John Huston’s 1969 historical comedy “Sinful Davey.” Although she concentrated primarily on stage and television work during the 1970s, Flanagan appeared in Peter Werner’s short film “In the Region of Ice,” which won the Academy Award for Best Live Action Short Film in 1977. Her early 1980s film credits included “Mr. Patman,” “Through Naked Eyes” and “Reflections.” In 1985, she starred in “James Joyce’s Women,” a film adaptation of her acclaimed one-woman stage production, portraying six different women drawn from Joyce’s life and literary works.

Her performance earned a Saturn Award for Best Supporting Actress.

In 1977, she created and starred in “James Joyce’s Women,” a one-woman production featuring six female characters from Joyce’s life and fiction. The play earned critical acclaim and became one of her signature theatrical achievements, eventually inspiring the 1985 film adaptation. Flanagan returned to Broadway in 2018 in Jez Butterworth’s “The Ferryman,” directed by Sam Mendes. Her performance as Aunt Maggie Far Away earned her a second Tony Award nomination for Best Featured Actress in a Play in 2019. She continued performing in theater into her 80s, appearing in a 2024 production of John B. Keane’s “Sive” at Dublin’s Gaiety Theatre. During the engagement, she was honored with a bronze handprint outside the theater in recognition of her contributions to Irish acting. She has also received multiple Irish Film and Television Awards, including a Lifetime Achievement Award in 2012.
Personal Life
In 1972, Flanagan married Irish psychiatrist and addiction specialist Garrett O’Connor. O’Connor was involved in Irish nationalist causes and became a prominent figure in addiction treatment, serving as the founding president of the Betty Ford Institute. The couple lived in the Los Angeles area for decades and were known for hosting gatherings attended by members of the Irish community and entertainment industry. They remained married until O’Connor’s death in September 2015. Flanagan has maintained close ties to Ireland throughout her career and has been an advocate for Irish cultural identity and the arts. After living in California for more than five decades, she returned to Ireland, settling in County Wicklow.
Real Estate
In 1972, Fionnula Flanagan and Garrett O’Connor purchased a home in Beverly Hills, California, for $41,000. The property, situated near Benedict Canyon and Mulholland Drive, became their longtime residence and a gathering place for friends and members of the Irish community in Los Angeles. Flanagan retained ownership of the house following her husband’s death in 2015. In December 2024, she listed the property for sale with an asking price of $2.8 million. She subsequently sold the residence as part of her relocation to Ireland, although the final sale price has not been publicly confirmed. In 2020, Flanagan also purchased a home in Rancho Mirage, California, for $522,000. From a Dublin stage debut in 1964 to an award nomination in 2026, Fionnula Flanagan’s six-decade career — and her $4 million fortune — were built the old-fashioned way: one acclaimed performance at a time.
