HBO's upcoming documentary FAYE explores Faye Dunaway's life and acting career. The documentary, which premiered at this year's Cannes Film Festival, also opens up about her struggles and painful childhood. It touches on her marriage and her relationship with her son, Liam Dunaway O'Neill. The documentary will be available to stream on Max starting July 13.

Born in 1980, Faye Dunaway and her second husband, Terry O'Neill, adopted Liam Dunaway O'Neill when he was only a week old. According to People Magazine, Faye and Terry filed for divorce in 1987, but continued to care for Dunaway O'Neill together.

Liam Dunaway O'Neill has appeared on the red carpet with his mother on several occasions. In fact, the two have also acted in a few projects. According to his IMDb page, Dunaway O'Neill made his acting debut with Faye Dunaway in the 2004 film Last Goodbye. In 2005, he starred opposite Chris Pine in Confession. His last acting appearance, however, was in the 2008 short film Al's Beef.

In August 2021, Liam Dunaway O'Neill spoke candidly about his transformation and weight loss. On Instagram, he wrote about how he fell into depression and weighed 209 pounds. In the post, he noted that he didn't like himself and was in a bad place until he started losing weight. He said, "After a while, I got a photo of myself sent to me and knew I had to do something. I decided to dedicate the next year to my mental and physical health."
