The Switch

Kassie (Jennifer Aniston), a smart, fun -- loving single woman who, despite her neurotic best friend Wally's (Jason 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.
