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 babyeven 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 neuroticson. From the people behind 'Little Miss Sunshine' and 'Juno' comes 'The Switch,' due in theaters this summer.
