Maria Bello is in final negotiations to take over for Maggie Gyllenhaal in Rebecca Miller's adaptation of her novel "
The Private Lives of Pippa Lee."
Gyllenhaal had hoped to complete her portion in the ensemble cast within two weeks in Connecticut, playing star Robin Wright Penn's mother in several flashback sequences. But when the new scheduling stretched out her shoot over five weeks, she chose to stay with Peter Sarsgaard and their newborn as he films "An Education" in the U.K.
