The near-future tale, set in Los Angeles, follows Phoenix as Theodore Twombly, a heartbroken man who falls hard for "Samantha" an advanced, intuitive operating system with a female voice (by Scarlett Johansson) that is insightful, sensitive and surprisingly funny.

Her opens in limited release December 18 in New York, Los Angeles and Toronto, and will go wide on January 10, 2014.
