The feature film adaptation of the guidebook of the same name by Heidi Murkoff and Sharon Mazel follows five couples as they going through the pregnancy process.

"I'm calling it. Pregnancy sucks! Making a human being is really hard. I have no control over my body or my emotions. Carebear, I'm sorry, all I want to do is punch you in the face," Banks declares.

The other couples -- played by Brooklyn Decker and Dennis Quaid; Anna Kendrick and Chace Crawford; Cameron Diaz and Matthew Morrison; and Jennifer Lopez (in a similar to 2010's The Back-Up Plan) and Rodrigo Santoro -- are all preparing for (and learning about) their new additions in their own way. Chris Rock, Joe Maganiello and Rebel Wilson co-star.

"Welcome to escrow, bitch."

Written by Shauna Cross and Heather Hach and directed by Kirk Jones, What to Expect When You're Expecting hits the big screen on May 11, 2012.
