JENNIFER ANISTON and JASON BATEMAN star in “The Switch,” an offbeat comedy about Kassie, a smart, fun-loving single woman who, despite her slightly neurotic best friend Wally’s 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 precocious—though slightly neurotic—son. From the people behind “Little Miss Sunshine” and “Juno” comes “The Switch," due in theaters this summer.
