An upcoming book by Daniel Day-Lewis' wife Rebecca Miller is heading for the big screen after impressing Hollywood producers. Actresses Robin Wright Penn, Julianne Moore and Winona Ryder have already signed up to star in the movie version of The Private Lives Of Pippa Lee. Miller, 45, - the daughter of playwright Arthur - says, "By the time I was done with the book, I felt I had enough juice to make a film. "Most of the time I will be writing books that are books and films that are films. But my curiosity for these characters meant that I wanted to explore them further." Miller previously directed the 2002 film Personal Velocity: Three Portraits, based on Personal Velocity, a collection of short stories she published in 2001.
