Ryan O’Neal, best known for his successful roles in 1970s films Love Story, Paper Moon and Barry Lyndon, has passed away at the age of 82.

The Oscar-nominated actor died on Friday with the news confirmed by his family. As of now, a cause of death is not yet known.

Born in Los Angeles in 1941, O’Neal took up boxing in school and developed an impressive physique before landing small television roles.

He made his on-screen debut in television series The Many Loves of Dobie Gillis (1960) and The Untouchables (1960) and later popped up in episodes of Bachelor Father (1961), Laramie (1961), Leave It to Beaver (1961), The Virginian (1963) and Perry Mason (1964).

After a recurring role as Tal Garrett in Big G (1962-64), O’Neal was then cast in America’s first prime-time soap opera Peyton Place. A television adaptation of the acclaimed 1955 film of the same name, the series helped O’Neal become a household name with his rugged good looks. He would play the role of sociable young man Rodney Harrington in a lengthy 501 episodes between 1964 and 1969 before hitting the big time in the 1970s.

Having starred in minor films like The Big Bounce (1969) and The Games (1970s), O’Neal then struck gold with his next role alongside Ali MacGraw in the romantic tearjerker Love Story (1970). The film centred on Oliver Barrett (O’Neal) an upper-crust Harvard undergraduate who found love and tragedy with working-class student Jenny (MacGraw).

Often cited as one of cinema’s greatest romance flicks, Love Story was a universal hit with critics and audiences with O’Neal earning a Golden Globe and Oscar nomination for Best Actor.

From then on, O’Neal’s star rose as he starred alongside Barbra Streisand as Howard Bannister in the screwball comedy What’s Up, Doc? (1972) as well as Wild Rovers (1971) and The Thief Who Came to Dinner (1973).

He then collaborated with his daughter Tatum on the comedic drama Paper Moon (1973) in which he played Depression-era conman Moses Pray.

Though the role earned him a second Globe nomination, he was overshadowed in the film by Tatum who went on to win the Best Supporting Actress Oscar at the age of just nine. However, this particular moment sparked the beginning of a difficult relationship between the pair that would last for decades.

Shortly after, O’Neal worked with acclaimed filmmaker Stanley Kubrick as the title character in the period epic Barry Lyndon (1975) before appearing in other 70s films like Nickelodeon (1976), A Bridge Too Far (1977) and The Driver (1978).

However, his star faded at the end of the 1970s with critics panning films like Oliver’s Story (1978), an unnecessary sequel to Love Story, and The Main Event (1979), a sports comedy featuring a reunion with Streisand.

O’Neal’s turbulent personal life kept him in the headlines starting with his long-term, tumultuous romance with Charlie’s Angels actress Farrah Fawcett. The pair were together between 1979 and 1997 and even collaborated on both the mini-series Small Sacrifices (1989), and the sitcom Good Sports (1991). They later reconciled in 2001 only for the relationship to end tragically with Fawcett’s death in 2009.

Back on the film front, O’Neal endured a series of critical flops including Green Ice (1981), So Fine (1981), Partners (1982), Fever Pitch (1985) and Tough Guys Don’t Dance (1987) though he also found respectability with flicks like Irreconcilable Differences (1985) and Chances Are (1989).

However, O’Neal’s filmography continued to falter with roles in the likes of Faithful (1996), Hacks (1997), Coming Soon (1999), The List (2000) and People I Know (2002). Towards the end of his acting career, he enjoyed recurring parts in series like Bull (2000-01), Miss Match (2003), Desperate Housewives (2005) and 90210 (2010).

His last two film roles came in the form of Slumber Party Slaughter (2014) and Knight of Cups (2015) as well as multiple guest appearances as Max Keenan, the estranged father of Dr. Temperance “Bones” Brennan in the crime series Bones (2006-17).

O’Neal is survived by four children from three different relationships including his actress daughter Tatum.
