Ever since he emerged with a stunning performance as an abused stepson in "This Boy's Life" (1993), actor Leonardo DiCaprio was expected to achieve greatness by critics and the public alike. DiCaprio met these expectations, thanks to an Oscar-worthy performance as a mentally challenged teenager in "What's Eating Gilbert Grape" (1993) and as a troubled teen in "Marvin's Room" (1996). While he became a bona fide star, nothing prepared him for the life-changing celebrity he achieved with the James Cameron's smash "Titanic" (1997). With this one film, DiCaprio went from a somewhat popular actor to an overnight teen idol and international media sensation, relentlessly hounded by the paparazzi. While he never wanted to reach such heights - he always thought of himself as an indie actor - DiCaprio had no choice but to ride the teen idol wave. Eventually, the furor died down and DiCaprio managed to complete the seemingly impossible transition from child actor to adult star, thanks in large part to his collaboration with director Martin Scorsese. Starting with the hyper-violent "Gangs of New York" (2002), DiCaprio and Scorsese made a series of films that seemed to revitalize each artist both creatively and in the market, culminating in the Oscar-winning crime epic, "The Departed" (2006). His transformation was complete with his star turns in Christopher Nolan's "Inception" (2010), Baz Luhrmann's "The Great Gatsby" (2013), and Alejandro González Iñárritu's "The Revenant" (2015), for which he finally won an Oscar. Because of his deep well of talent and determination, DiCaprio was able to accomplish the rare feat of fulfilling his early youthful promise.
