Spike Jonze (Where The Wild Things Are, Being John Malkovich, Adaptation.) is clearly the mind behind this oddball modern romance. Joaquin Phoenix stars as a lonely writer who manages to fall in love with the automated voice behind his new smartphone's operating system (Scarlett Johansson in a fine, vocal-only performance). Both surrealist and screwball, this unconventional rom-com is played perfectly straight--making it thoughtful and just a bit chilly around the edges. 126 minutes R.
