Too Rich: The Secret Life of Doris Duke is a 1999 American four-part television miniseries starring Lauren Bacall and Richard Chamberlain which was first broadcast on CBS on February 21 and 23, 1999. It was based primarily on the book The Richest Girl in the World by Stephanie Mansfield (Pinnacle Books issued a special movie tie-in edition of the book in February 1999) as well as Bob Colacello's two in-depth articles about Ms. Duke in Vanity Fair. Colacello was the magazine's authority on Doris Duke.
