Gordon-Levitt plays Tom Hansen in this offbeat romantic comedy directed by Marc Webb. A trained architect who writes greeting cards for a living, his character falls in love with his co-worker Summer, played by actress Zooey Deschanel. Their contrasting beliefs about love and relationships eventually end their 500-day romance.
He develops a mildly delusional obsession over a girl onto whom he projects all these fantasies. He thinks she’ll give his life meaning because he doesn’t care about much else going on in his life. A lot of boys and girls think their lives will have meaning if they find a partner who wants nothing else in life but them. That’s not healthy. That’s falling in love with the idea of a person, not the actual person.
