Notable for his major roles in the 1980s movies April Fool's Day and The Escape Artist, O'Neal also appeared in a 1991 video production titled Ghoulies Go to College.
He made his big screen debut in the 1976 comedy movie Nickelodeon.
New York Times arts critic Vincent Canby wrote a glowing 1982 review of O'Neal's acting work.
He grew up in Los Angeles in a family of entertainers; his parents, Ryan O'Neal and Joanna Moore, were both actors, and his sister, Tatum O'Neal, won an Academy Award at the age of ten for her role in Paper Moon.
O'Neal was convicted of negligent boat operation after a boat he was piloting was involved in an accident that resulted in the death of director Francis Ford Coppola's son Gian-Carlo Coppola.
