Warner Bros. has released the trailer for Katherine's new romantic drama "Life As We Know It" which is due to hit the big screen on October 8th. The film, directed by Greg Berlanti and shot in Atlanta during late Fall 2009, also stars Josh Duhamel, Christina Hendricks and Josh Lucas.

The theatrical trailer was first seen at the ShoWest Motion Picture Industry Convention in Las Vegas back in March and was very well received by attendees.

In "Life As We Know It", Katherine plays up and coming caterer Holly Berenson with Duhamel portraying promising network sports director, Eric Messer. After a disastrous first date the two decide that the only thing they have in common is their dislike for each other and their love for their goddaughter, Sophie. However, their lives are soon turned upside down when their mutual best friends are killed in an accident and they are named as carers for the deceased's orphaned daughter.
