‘Expecting’ something

New York Times best-selling mom-to-be guidebook What to Expect When You’re Expecting transforms into a romantic comedy of toddler proportions this Friday. Nanny McPhee’s Kirk Jones directs an ensemble cast of five couples plowing through the ups and downs of pregnancy and parenthood in a story that proves no matter how prepared parents think they are, life finds a way to deliver something unexpected. Cameron Diaz, Jennifer Lopez, Chris Rock and Dennis Quaid lead the cast that also includes Elizabeth Banks, Chase Crawford, Anna Kendrick and model-turned-actress Brooklyn Decker. Rated PG-13.
