Smiley Face (2007)

Jane F, an unsuccessful slacker actress, is having a bad day. And it's getting more outrageous and comically surreal by the minute. Jane's misadventures begin when she treats herself to a batch of cupcakes left unattended by her psycho roommate that prove not as innocent as they appear, Soon, she is trying to cross town so she can repay an unforgiving drug dealer, attend an audition, and somehow replace the precious cupcakes. Bumming a ride from her roommate's friend--who is totally infatuated with her--she sets out on a long, strange trip. And, when the original manuscript of the Communist Manifesto falls into her hands, things really get out of control.
