500 Days of Summer Official Full Length Trailer

The film tells the story of the relationship between a woman, Summer (Zooey Deschanel), who doesn't believe in true love and a man, Tom (Joseph Gordon-Levitt), described as a hopeless romantic,[4] who falls in love with her. Over a span of 500 days, the story moves in a non-linear fashion from the perspective of Tom, who goes from ecstatic giddiness one moment, indulging in a fantasy song and dance sequence at one point, to crippling depression the next. It features two songs ("Us" and "Hero") by Regina Spektor, and "Sweet Disposition" by Melbourne-based band The Temper Trap.
