A few years ago, a group of friends (Jon & Pete Reiling, Brian Grunert and Biff Henrich) created a short film for the Buffalo 48-hour Film Project. Their entry, "Captain Buffalo," is considered by many to be the "Citizen Kane" of five minute superhero movies; it also inspired the above illustration. See the original movie here:
