"500 Days with Her" is a charming and offbeat romantic comedy-drama that tells the story of Tom Hansen (Joseph Gordon-Levitt), a young architect who falls in love with his boss, Summer (Zooey Deschanel), a quirky and free-spirited woman. The movie takes a non-linear approach, jumping back and forth between the 500 days of their relationship, as Tom tries to navigate his feelings and understand Summer's unconventional nature.
