I had no idea a feature doc on the Williams sisters was in production; then again, it  really shouldn't be much of a surprise. They ARE the world-famous Williams sisters.

Directed by Maiken Baird, an independent documentary filmmaker who specializes in international and political affairs (she produced the acclaimed Client 9: The Rise and Fall of Eliot Spitzer, with Academy Award winning director and producer Alex Gibney, who also produced this documentary).

The film is said to take…

… an honest and unfiltered look into the remarkable lives of sisters and tennis legends Venus and Serena Williams. Through the prism of one year in the lives of Venus and Serena, the film tells the untold story of how an unlikely family from Compton raised two daughters to be the best tennis players in the world. It explores not only the complex family dynamic, unique and unprecedented in the history of any sport, but also the multifaceted relationship the sisters have with the tennis world.

By the way, long-time Spike Lee editor Sam Pollard (and director of Slavery By Another Name), cut this Williams sisters doc as well.

Its debut at the Toronto International Film Festival in September, will be the film's world premiere.
