(CNN) Warren Buffett has long been a source of fascination, and not just for Berkshire Hathaway investors who flock to hear what the "Oracle of Omaha" has to say about money. HBO thus provides a sort-of public service to posterity with "Becoming Warren Buffett," and those who watch the feature-length documentary will feel the richer for it. With a net worth of $67 billion (give or take), the 86-year-old Buffett is the ultimate self-made man. Beyond direct-to-camera interviews, part of the material comes from Buffett addressing a group of high school kids, dispensing homespun wisdom life and money that's self-effacing but infused with considerable authority. Once terrified of pubic speaking, Buffett credits the Dale Carnegie course for having helped him overcome that fear.
