Spike Jonze has been creating marvelous worlds — and getting inside our heads in the process — ever since Being John Malkovich. His latest film, Her, takes things a timely step further. It's the story of a lonely man, played by Joaquin Phoenix, who falls in love with an "artificially intelligent operating system" voiced by none other than Scarlett Johansson. It's like Siri has a soul, and while we were already looking forward to this movie, after this first glimpse Her has rocketed to the top of our must-see list. Check it out.
