Hollywood actor Tobey Maguire credits Titanic star Leonardo Dicaprio with teaching him how to act. The Spider-Man actor was 17 when he met 18-year-old DiCaprio on the set of This Boy's Life - and he was in awe of the young star's thespian talents. He says, "I remember going to the set of This Boy's Life and I went over to go goof around with him before a take, and he was sitting there, thinking about stuff. "Then we went into the scene and I remember just being floored at how talented he was. He just clicked into a different gear on that movie from what he was doing before."
