What an interesting story and movie...could you picture a man and the operating system of the man's smart phone fall in love with each others? The actor is so different after falling in love with the operating system.
The voice of Samantha (the operating system of the man's smart phone) by Scarlett Johansson is really really sexy and great to make "Her" so real ! The performance of Joaquin Phoenix (the actor) is not bad.
Watching the movie, I feel the loneliness of we people. Hope that is not our life of the future !
