Less than two months after actress Scarlett Johansson stepped in to replace Samantha Morton as the voice of Her, the first trailer has debuted. Joaquin Phoenix stars as Theodore Twombly, a lonely writer who purchases a new computer operating system that is personalized to each individual user. When the system is installed, Theodore meets "Samantha" (Scarlett Johansson) and begins to fall in love with this artificial voice. In addition, we have the first poster for director Spike Jonze's unconventional romantic comedy, arriving in theaters November 20.

<strong><em>Her</em></strong> Poster

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.
