New York ? Oprah Winfrey’s quarter-century run on daytime TV may be accompanied by a TV film dramatizing her life.

Veteran producer Larry A. Thompson said Monday the planned two- or four-hour Winfrey film will be based on Kitty Kelley’s tell-all biography. Thompson says he has optioned it for six figures.

The TV project is expected to air in September 2011, which would coincide with the end of Winfrey’s weekday talk show.

He calls himself “a huge fan” of Winfrey’s and says he’s shopping the project to networks he declined to specify. An unknown will likely be cast to play Winfrey.

A spokesman for Winfrey’s Chicago-based Harpo Productions declined to comment.
