NEW YORK (AP) - You could always tell which sound booth Scarlett Johansson was using to record her lines for the movie "Her." Johansson's booth was the one with fogged up windows. Johansson is the voice of Joaquin Phoenix's computer operating system. He ends up falling in love with her voice and one thing leads to another. Johansson tells W magazine that "the vocal work was extremely intimate." She says when she read the lines of her sex scenes "the windows fogged up."
