Cannonball is a short film focused on a very specific side effect of The Great Recession: A glut of foreclosed homes in Fresno, California, and tons of empty swimming pools that have attracted legions of the city’s skateboarders. Armed with sump pumps and skate decks, the subjects in Cannonball provide a unique look at the nationwide fallout of the economic crisis. Instead of seeing the country through the eyes of those who have lost so much, we instead see the opportunities these losses have created.
