Smiley Face (2007)

Jane is an actress/slacker whose day goes seriously out-of-control when she tries to balance competing agendas to get all the items on her "to do" list done. Complications take the form of a nerd obsessed with her, an audition that goes awry, a depleted bank account, and a series of misadventures that include an inadvertent heist, an escape from the cops, and a tour of Los Angeles that shows the city to be a formidable opponent!
