Mary Dinkle, a chubby 8-year-old Australian girl, and Max Horovitz, an obese, middle-aged New Yorker with Asperger's syndrome, are a pair of unlikely pen pals in this quirky clay animation feature from writer-director Adam Elliot. Corresponding for two decades, the friends delve into a variety of topics, including sex, kleptomania, psychiatry, taxidermy and more. Toni Collette and Philip Seymour Hoffman provide the voices of Mary and Max.
