Christopher Brosnan, the estranged son of actor Pierce Brosnan, was recently seen in public in London, marking a rare sighting. Christopher, 51, was adopted by Pierce after the death of his biological father, Dermot Harris, and has struggled with drug addiction, leading to a strained relationship with Pierce. Despite having worked on several of his father's films, Christopher's substance abuse issues have led Pierce to cut him off nearly two decades ago. Christopher's mother, Cassandra Harris, and his sister, Charlotte, both died of ovarian cancer, deepening his personal struggles. In 2022, Pierce acknowledged Christopher in an Instagram post on Father's Day, expressing love for all his sons. Christopher's public appearance involved running errands and was noted for his casual attire.
