VIDEO: New Trailer for Spike Jonze's HER, Starring Joaquin Phoenix

Written and directed by Spike Jonze, HER stars Oscar nominees Joaquin Phoenix ("The Master," "Walk the Line"), Amy Adams ("The Master," "Doubt"), Rooney Mara ("The Girl With the Dragon Tattoo"), Olivia Wilde (upcoming "Rush") and Scarlett Johansson ("Lost in Translation"). Check out a new trailer for the film below!

Written and directed by Jonze, HER is set in Los Angeles, in the near future and follows Theodore Twombly (Joaquin Phoenix), 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 and unique entity in its own right. Upon initiating it, he is delighted to meet "Samantha," a bright, female voice (Scarlett Johansson), 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. HER is an original love story that explores the evolving nature-and the risks-of intimacy in the modern world.

It is produced by Megan Ellison, Spike Jonze and Vincent Landay. Daniel Lupi, Natalie Farrey and Chelsea Barnard serve as executive producers. The film reunites many of Jonze's longtime creative collaborators, including production designer KK Barrett, editor Eric Zumbrunnen and costume designer Casey Storm, who worked together on "Where the Wild Things Are," "Adaptation." and "Being John Malkovich." Joining them is director of photography Hoyte Van Hoytema ("Tinker Tailor Soldier Spy") and editor Jeff Buchanan (HBO's "Tell Them Anything You Want: A Portrait of Maurice Sendak," which Jonze co-directed). The music is composed by Arcade Fire.

HER is a Warner Bros. Pictures presentation of an Annapurna Pictures Production. It will be distributed by Warner Bros. Pictures, a Warner Bros. Entertainment Company.
