The feature-film debut of music video director Marc Webb is a flouncy romantic comedy starring Joseph Gordon-Levitt (best known for 1990s sci-fi sitcom Third Rock from the Sun) as Tom, a wannabe architect working as a greetings card writer, who falls in and out of love with Summer (Zooey Deschanel), a beautiful if mercurial woman who starts work as his boss's secretary. The film jumps backwards and forwards in time throughout our hero's 500-day infatuation with Summer, who unfortunately for Tom firmly refuses to believe in love. Gordon-Levitt's soft-hearted, love-struck performance is heartbreaking to watch - although it is played mostly for comedy - and really demonstrates how confused a man in love can get. However, Webb's offbeat direction is occasionally disjointed, giving the appearance of a movie made up of a string of short films spliced together. The idea of analysing a relationship at different points in time is certainly fresh and interesting, but the director's inability to control the pace means the end result is a bit twee.
