July 16th Update:
A new project tentatively called Mommy & Me is being shopped around that will find Meryl Streep and Tina Fey starring alongside each other for director Stanley Tucci.
The combination of Streep and Fey would be dynamite at the box office. Streep has hit a hot streak late in her career thanks to the likes of The Devil Wears Prada, Mamma Mia!, Julie & Julia and It's Complicated. Fey has parlayed her television success on 30 Rock into hits such as Baby Mama and Date Night.
