The first trailer for director Spike Jonze's new movie, "Her," shows a peculiar romance.
A lonely writer, played by Joaquin Phoenix, falls in love with his artificially intelligent operating system, voiced by Scarlett Johansson.

"Her," which hits theaters November 20, also stars Amy Adams, Rooney Mara, Olivia Wilde, and Chris Pratt.
