LOS ANGELES – Actor Ryan O’Neal, the 1970s Hollywood heart-throb who starred in such films as Love Story, What’s Up, Doc? and Paper Moon, died on Dec 8 at age 82, his son said in an Instagram post.

No cause of death was given. O’Neal, also known for his long-time romance with the late actress Farrah Fawcett, revealed in 2012 that he had been diagnosed with prostate cancer, though he said then that his prognosis was good.

A Los Angeles native who trained as an amateur boxer before taking up acting, O’Neal made his showbiz breakthrough in 1964 when he landed a role in the hit prime-time television soap opera Peyton Place.

He is perhaps best remembered for his Oscar-nominated star turn opposite Ali MacGraw in the 1970 romantic drama Love Story, a box-office sensation adapted from Erich Segal’s popular novel of the same title.

He went on to star opposite Barbra Streisand in What’s Up, Doc?, a 1972 screwball comedy directed by Peter Bogdanovich, who also directed O’Neal in the 1973 hit film Paper Moon, which co-starred the actor’s then-young daughter.

Her debut role in the Depression-era drama as a precocious, cigarette-smoking orphan earned Tatum O’Neal an Academy Award at the age of 10 for best supporting actress.

She claimed in a 2004 memoir that she suffered years of parental abuse and fits of jealousy from her father, and that he had introduced her to drugs, leading to an estrangement of nearly 25 years.

Ryan O’Neal disputed his daughter’s claims, and the two eventually reconciled, appearing in a biographical docuseries together in 2011 called Ryan And Tatum: The O’Neals.

“My dad passed away peacefully today, with his loving team by his side supporting him and loving him as he would us,” her half-brother, Patrick O’Neal, wrote on Instagram on Dec 8 in a tribute, adding that his father “has always been my hero”. REUTERS
