Alfredo James "Al" Pacino (born April 25, 1940) is an American film and stage actor and director. He is best known for his roles as Michael Corleone in The Godfather trilogy, Sonny Wortzik in Dog Day Afternoon, Tony Montana in Scarface, Carlito Brigante in the 1993 film Carlito's Way, Frank Serpico in Serpico, Lieutenant Colonel Frank Slade in Scent of a Woman, and Roy Cohn in Angels in America. He won the Academy Award for Best Actor in 1992 for his role in Scent of a Woman after receiving seven previous nominations.

Pacino was born in East Harlem, Manhattan, the son of Italian-American parents Rose (née Gerardi) and Salvatore Alfred Pacino, who divorced when he was two years old. His mother subsequently moved to the South Bronx, to live with her parents, Kate and James Gerardi, who originated from Corleone, Sicily. His father moved to Covina, California, working as an insurance salesman and owner of a restaurant called Pacino's Lounge, which closed in 1992. Pacino attended a school officially named High School of Performing Arts, a division of the Fiorello H. La Guardia High School of Music and the Arts in New York City, the main school of which was attended by Godfather II costar Robert De Niro. Pacino flunked nearly all of his classes except English and dropped out of school at the age of 17. His mother disagreed with his decision; they had an argument and he left home. He worked at a string of low-paying jobs, including messenger boy, busboy, janitor and postal clerk, in order to finance his acting studies.

He acted in basement plays in New York's theatrical underground, and then joined the Herbert Berghof Studio (HB Studio), where he met acting teacher Charlie Laughton, who became his mentor and best friend. During this period, he was frequently unemployed and homeless, and sometimes had to sleep on the street, in theaters or at friends' houses. In 1962, his mother died at age 43. The following year, his grandfather, James Gerardi, one of the most influential people in his life, also died.
