Leonardo DiCaprio is one of the most popular and critically acclaimed movie stars of the modern era, but he'd have fit in perfectly during the Golden Age of Hollywood. The 46 year-old is very selective about the projects he chooses to sign on to, makes a point of collaborating with the finest directors in the industry, lends other filmmakers a hand through his Appian Way Productions, rarely gives interviews when he's not on the promotional trail and can regularly be spotted in glamorous locations around the world with a supermodel on his arm.
