Life As We Know It hits theaters on the plum, pre-holiday release date of December 22, which might seem odd for a movie starring Katherine Heigl and Josh Duhamel as two people falling in love. But the movie has a secret weapon-- it might actually be pretty good. The first trailer for the movie has hit the web at Yahoo! Movies, and it's the same one that played to a thrilled crowd at ShoWest a few weeks ago. Yes, the movie is a romantic comedy, but it also seems to have an unusual depth, and it has the added benefit of seeming pretty funny as well-- even with a few too many poop jokes.

Duhamel and Heigl star as two people who suffer a horrible date together and vow never to see each other again, only to be named as the parents of a child when their mutual friends die in a car accident. It's the classic setup for two mismatched people to fall in love, but with a baby in the mix to make it even more difficult. Yes, I know none of this sounds remotely appealing yet, but just watch the trailer below and find out for yourself that Life As We Know It might be worth your time.
