Warner Bros. has released a new trailer for Spike Jonze’s (Where the Wild Things Are, Adaptation, Being John Malkovich) upcoming acclaimed romantic drama Her. The film centers on a heartbroken, lonely writer who develops an unlikely relationship with his newly purchased operating system (voiced by Scarlett Johansson) that’s designed to meet his every need. Amy Adams, Rooney Mara, and Olivia Wilde also star. Her opens in limited release on December 18th.

Set in Los Angeles, slightly in the future, “her” follows Theodore Twombly, a complex, soulful man who makes his living writing touching, personal letters for other people. Heartbroken after the end of a long relationship, he becomes intrigued with a new, advanced operating system, which promises to be an intuitive entity in its own right, individual to each user. Upon initiating it, he is delighted to meet “Samantha,” a bright, female voice, who is insightful, sensitive and surprisingly funny. As her needs and desires grow, in tandem with his own, their friendship deepens into an eventual love for each other. From the unique perspective of Oscar-nominated filmmaker Spike Jonze comes an original love story that explores the evolving nature—and the risks—of intimacy in the modern world.
