Trailer for The Switch.
Jennifer Aniston stars alongside Jason Bateman in this offbeat comedy as Kassie, a smart, fun-loving single woman who, despite her neurotic best friend Wally's (Bateman) objections, decides it's time to have a baby?even if it means doing it by herself... with a little help from a charming sperm donor (Patrick Wilson). But, unbeknownst to her, Kassie's plans go awry because of a last-minute switch that isn't discovered until seven years later when Wally finally gets acquainted with Kassie's cute--though slightly neurotic--son.
