Last April, the dirt-digging author Kitty Kelley made a splash with her unauthorized biography of Oprah Winfrey. Now, a veteran film and television producer named Larry A. Thompson has announced plans to turn the gossip-filled book into a big-screen biopic. The movie is slated to be released in September 2011—the same month that the daytime queen plans to take her long-running show off the air—but the key part is, as of yet, uncast; Thompson has reportedly said that he’s likely to choose an unknown actress for the starring role. Maybe so, but we can think of several big-name stars we’d be interested to see stepping in to Oprah’s Louboutin’s.
