Leonardo Dicaprio has no plans to ditch acting for college because he gets all the education he needs preparing for new film roles. The TITANIC actor has boosted his brain-power over the years through thorough research, gaining a new area of expertise every time accepts a role. He tells Empire magazine, "Every movie I do - like Gangs of New York and The Aviator - is like taking a college course on that subject matter, and each time I've gotten involved with these movies it's been like a giant tutorial. "You have to be a detective and you have to investigate. You have to be a historian in that regard, so, yeah, it's like taking courses, which is great, 'cause I never went to college."
