Bring on the Baby Bjorns: the trailer has just been released for What to Expect When You’re Expecting, an upcoming ensemble romcom that’s based on the classic pregnancy how-to tome. Elizabeth Banks, Brooklyn Decker, Cameron Diaz, Dennis Quaid and Matthew Morrison are only a few of the A-listers playing parents-to-be. Like 2009’s He’s Just Not That Into You, the celeb-saturated comedy bears only a passing resemblance to its self-help inspiration; it’s a series of linked vignettes dealing with the mishaps and misadventures of early parenthood. The only piece of parenting advice we can glean from the trailer is to never, ever leave your children alone with their father and his friends. -Allison Friedman
