Author Kitty Kelley has reportedly sold the movie rights to her unauthorized Oprah Winfrey biography for a “TV movie or miniseries.”

E! Online has the scoop: “Kelley finalized a six-figure deal with Larry Thompson, a veteran producer behind biopics on Lucille Ball and Desi Arnaz, Sonny and Cher, and the Duke and Duchess of Windsor. Thompson says that the plan is to develop the project to coincide with Winfrey’s final syndicated episode in September 2011, with an unknown actress in the lead role.”

In the Media Beat show, Kelley (pictured)explained her work: “This book is not a takedown of Oprah by any means. There are many, many people on the record talking about her in a most admirable fashion.”
