Few actors in the world have had a career quite as diverse as Leonardo DiCaprio's. DiCaprio has gone from relatively humble beginnings, as a supporting cast member of the sitcom Growing Pains (1985) and low budget horror movies, such as Critters 3 (1991), to a major teenage heartthrob in the 1990s, as the hunky lead actor in movies such as Romeo + Juliet (1996) and Titanic (1997), to then become a leading man in Hollywood blockbusters, made by internationally renowned directors such as Martin Scorsese and Christopher Nolan.

Leonardo Wilhelm DiCaprio was born November 11, 1974 in Los Angeles, California, the only child of Irmelin DiCaprio (née Indenbirken) and former comic book artist George DiCaprio. His father is of Italian and German descent, and his mother, who is German-born, is of German and Russian ancestry. His middle name, "Wilhelm", was his maternal grandfather's first name. Leonardo's father had achieved minor status as an artist and distributor of cult comic book titles, and was even depicted in several issues of American Splendor, the cult semi-autobiographical comic book series by the late 'Harvey Pekar', a friend of George's. Leonardo's performance skills became obvious to his parents early on, and after signing him up with a talent agent who wanted Leonardo to perform under the stage name "Lenny Williams", DiCaprio began appearing on a number of television commercials and educational programs.
