Struggling as an actor for a number of years upon moving to New York City in 1969, Stallone found gradual work in films such as The Lords of Flatbush (1974). He achieved his greatest critical and commercial success starting in 1976 with his iconic role as boxer Rocky Balboa in the first film of the successful Rocky franchise, which he also wrote.[4] In 1977, he became the third actor in history to be nominated for two Academy Awards for Best Original Screenplay and Best Actor. He portrayed the PTSD-plagued soldier John Rambo in First Blood (1982), a role he would play across five Rambo films (1982–2019). From the mid-1980s to the late 1990s, Stallone would go on to become one of Hollywood’s highest-paid actors acting in action films such as Cobra (1986), Tango and Cash (1989), Cliffhanger (1993), Demolition Man (1993), and The Specialist (1994). He received a star on the Hollywood Walk of Fame in 1984.

Stallone continued his established roles in Rocky Balboa (2006) and Rambo (2008) before launching The Expendables film franchise (2010–present), in which he starred as the mercenary Barney Ross. In 2013, he starred in the successful film Escape Plan and appeared in its sequels. In 2015, he returned to Rocky again with Creed, in which a retired Rocky mentors former rival Apollo Creed’s son Donnie Creed. The film brought Stallone widespread praise and his first Golden Globe Award, as well as a third Academy Award nomination, having been first nominated for the same role 40 years prior. Since 2022, he has starred in the Paramount+ crime series Tulsa King.

Sylvester Gardenzio Stallone[5][6][7] was born in the Hell’s Kitchen neighborhood of New York City’s Manhattan borough[8] on July 6, 1946,[9] the elder son of women’s professional wrestling promoter Jacqueline “Jackie” Stallone (née Labofish; 1921–2020) and hairdresser Francesco “Frank” Stallone Sr. (1919–2011). His mother was an American from Washington, D.C. with Breton French[11] and Ukrainian Jewish ancestry, while his father was an Italian immigrant from Gioia del Colle[10] who moved to the U.S. in the 1930s.[15][16] His younger brother is actor and musician Frank Stallone.[10] Many biographies of Stallone indicate that his birth name is “Michael Sylvester Gardenzio Stallone” and his mother explained in an interview that she originally named him “Tyrone” because she admired the actor Tyrone Power, but Stallone’s father changed it to “Sylvester”. His nickname as a child was “Binky” but he chose to go by the nickname of Mike/Michael after schoolmates began calling him “Stinky”.[5][6][7] His middle name “Gardenzio” is an alteration of the Italian given name “Gaudenzio” and he usually shortened it to “Enzio”.

Complications during Stallone’s birth forced his mother’s obstetricians to use two pairs of forceps while delivering him, accidentally severing a nerve in the process.[17][18] This caused paralysis of the lower left side of his face (including parts of his lip, tongue, and chin) which gave him his signature snarling look and slurred speech.[18][19] As a result, he was bullied in his childhood, with which he coped by getting into bodybuilding and acting.[20] He spent part of his infancy in foster and boarding care, rejoining and moving back with his family to Maryland when he was five. In the early 1950s, his father moved the family to his mother’s native Washington, D.C. to open a beauty school. In 1954, his mother opened a women’s gym called Barbella’s. He initially stayed with his father following his parents’ divorce when he was 11, but joined his remarried mother in Philadelphia when he was 15.
