The romantic comedy is set to begin shooting this summer and is scheduled for release May 11, 2012. Banks will play an author and owner of The Breast Choice boutique who is militant in her beliefs about what makes a good mother until she gets pregnant for the first time. Banks, who recently booked a role in Lionsgate’s The Hunger Games, is repped by UTA and Untitled Entertainment.
