'I'M THE KING OF THE WORLD' That was the cry from Leonardo DiCaprio as he stood astride the bow in Titanic - the movie that would go on to smash all records, raking in a whopping GBP1.1 billion worldwide. Now, few Hollywood movers and shakers would dispute that statement as Leo has rocketed to become one of the highest paid actors in the world. And his position looks set to be secure after an incredible 2013 which saw Hollywood's hottest talent appearing as the eponymous Jay Gatsy in the Great Gatsby, following swiftly on the heels of the great success of Quentin Tarantino's blockbuster, Django Unchained. Yet, although he's spent over 15 years at the top of his profession, Leonardo remains something of an enigma - his often daring movie choices suggest an actor still striving for perfection.
