Leo has become one of the highest paid actors in the world and his position looks set to be secure for some time to come as the release of the new 3D version of "Titanic "heralds another sensational year in the life of Hollywood's hottest talent. The year will also see him take on the lead role in a new adaptation of "The Great Gatsby" and see him cast as a villain in Quentin Tarantino's new blockbuster "Django Unchained." It's a far cry from the heartthrob's humble beginnings when he had to scrape for parts in TV commercials and soap operas before catching the eye in Baz Luhrmann's stylish "Romeo and Juliet" and then achieving worldwide superstardom with "Titanic." Cementing his reputation with captivating performances in films like" Catch Me If You Can "and "The Departed," DiCaprio won a Golden Globe for his portrayal of Howard Hughes in "The Aviator." A keen environmentalist and conservationist, he has given millions to good causes around the globe and has never been shy about wearing his political ideas on his sleeve. Although he's spent more than 15 years at the top of his profession, Leonardo remains something of an enigma. He has famously dated some of the world's most beautiful women, but seems no nearer to settling down, and his often daring movie choices suggest someone still striving for perfection despite his stunning successes.
