The first poster is out for The Switch, Jennifer Aniston is starring in yet another romantic comedy, acting alongside leading man Jason Bateman. The film features Aniston as Cassie, a single woman living in New York who decides to have a baby by way of artificial insemination, despite the objections of her neurotic best friend, Wally (Bateman). Wally quickly becomes jealous of the handsome and charismatic donor she has selected (played by Watchmen’s Patrick Wilson), and in a drunken stupor, substitutes his own sperm in place of Wilsons’. Seven years later, he meets his son when Aniston moves back to New York, and has to decide how to reconcile himself to the situation. The Switch is directed by Blades of Glory helmers Josh Gordon and Will Speck. The screenplay is written by Allan Loeb (Things We Lost in the Fire, 21, Wall Street: Money Never Sleeps).
