Samantha, voiced by Scarlett Johansson, not only checks his emails and organizes his life but engages Theodore playfully in banter and late night conversations.
As Theodore keeps conversing with Samantha, things get thornier. "What's it like to be alive in that room right now?" the operating system asks. He eventually professes his love for "her."
The film, written and directed by Jonze (Where the Wild Things Are, Adaptation), is set for release Nov. 20. The trailer is set to the Yeah Yeah Yeah's "Skeletons."
