Tatum O'Neal's Real Name: Tatum Beatrice O'Neal

Quick answer: Tatum O'Neal's documented full name is Tatum Beatrice O'Neal. Britannica lists that form as an also-known-as and dates her birth to November 5, 1963, in Los Angeles, California. Encyclopedia.com, reprinting Contemporary Theatre, Film and Television, independently uses the full name Tatum Beatrice O'Neal and the same date and city (Britannica; Encyclopedia.com).

Real name and early life

She is known professionally as Tatum O'Neal. Both sources agree on Tatum Beatrice O'Neal and on a Los Angeles birth on November 5, 1963. Britannica and Encyclopedia.com both identify her parents as the actors Ryan O'Neal and Joanna Moore (Encyclopedia.com also gives the mother's professional name, Joanna Cook, as Moore). Ryan O'Neal does not have a live RealNameOf biography and is not linked here. Britannica says that when she was eight, director Peter Bogdanovich approached her father and her about costarring in a film based on Joe David Brown's novel Addie Pray (1971), although Tatum had never acted before.

Career highlights

Britannica says that at age 10 she became the youngest person to win an Academy Award in competition, receiving the Oscar for best supporting actress as Addie Loggins in Paper Moon (1973), and that she also won a Golden Globe for most promising new actress. The Golden Globes independently list a 1974 win for New Star of the Year — Actress and a 1974 nomination for best actress in a musical or comedy, both for Paper Moon (Golden Globes). Encyclopedia.com independently records Paper Moon as her film debut and lists later credits including The Bad News Bears (1976), Nickelodeon (1976), International Velvet (1978), Little Darlings (1980), Basquiat (1996), and The Scoundrel's Wife (2002). Britannica independently discusses The Bad News Bears, Nickelodeon, International Velvet, Little Darlings, Basquiat, and The Scoundrel's Wife. It also notes that she portrayed an enterprising prop girl in Nickelodeon, which featured her father and Burt Reynolds, and that she starred with Christopher Plummer and Anthony Hopkins in International Velvet (1978), a sequel to National Velvet (1944). Encyclopedia.com lists additional credits including the television movie Woman on the Run: The Lawrencia Bembenek Story (1993), a 1984 appearance on Faerie Tale Theatre, and a New York stage debut in A Terrible Beauty at the Provincetown Playhouse in 1992.
