Josh Hartnett (Pearl Harbor) and Radha Mitchell (Silent Hill) star as Donald and Isabelle in Mozart And The Whale, a heartwarming romance about two people with a form of autism called Asperger's Syndrome. Donald, a good-natured but hapless cab driver with a knack for numbers, falls head over heels for the beautiful but complex Isabelle when she joins the autism support group he leads. Their first date, which occurs on Halloween, sets the tone for a budding romance that helps them establish their niche in a fascinating and quirky universe.
