LOS ANGELES (Reuters) - Born of Hollywood, acting as a teenager, Oscar-nominated by age 19, Leonardo DiCaprio is a product of the film studio's star-making machine.
He made young women swoon in the biggest box office hit of all-time, 1997's "Titanic," but his youthful looks meant the transition to strong, leading man roles would be difficult. Yet, as he left his 20s and entered his 30s, he earned Oscar nominations for playing Howard Hughes in 2004's "The Aviator" and two years later, a gem smuggler in "Blood Diamond."
He has become an activist for environmental issues, making a global warming documentary, "The 11th Hour."
Donald De Line, producer of DiCaprio's new spy thriller "Body of Lies" dealing with the CIA and the wars in Afghanistan and Iraq, called him "an intellectually curious man who has a mature world view and way of looking at things."
