OMAHA, Neb. -- Billionaire Warren Buffett's life and the way he made his fortune as an investor will be the focus of a new documentary on HBO next year.

The "Becoming Warren Buffett" documentary will debut Jan. 30.

The film uses Buffett's own words and interviews with friends and family members to explore what allowed him to become so successful at picking stocks and companies to buy.

Buffett's lifestyle in his hometown of Omaha, Nebraska, also will be highlighted. Buffett routinely drives himself to work at Berkshire Hathaway, where he studies businesses and decides where best to invest the conglomerate's cash.

Buffett also discusses his decision to give his fortune away to the Bill & Melinda Gates Foundation and four Buffett family foundations.
