Al Pacino:
Perhaps Pacino’s most memorable characters like this one from Scarface (the other as Michael Corleone in the The Godfather trilogy) are because Pacino knew of crime and homelessness as a teen and tween. Frustrated and disinterested in school in New York, Pacino drifted as an adolescence and got into fights and petty crime. Determined to become a stage actor, the high-school dropout worked odd jobs and slept in shelters and park benches at times before he got his big break in theaters.
