In (500) Days of Summer, Tom Hansen (Joseph Gordon-Levitt) reminisces his past relationship with Summer Finn (Zooey Deschanel).
The story is told in non-linear fashion, which is quite interesting and serves the film well. It's one of the best romantic comedy movies I've watched so far. The characters just seem so "real". (500) Days of Summer is a great, great, great movie with a wonderful soundtrack.
(And, no, I'm not angry at Summer or anything.)
