Continuity mistake: At the beginning of the film, protesters chase Harold through downtown traffic until he dives into his friend Todd's vehicle; whereupon the protesters urinate on Todd's windshield and splatter fecal matter across his driver's side window. For several scenes thereafter, the fecal splatter repeatedly changes shape, orientation and quantity on the side window, actually gaining mass in some shots.
