In today’s episode of Bloodworks, Scott Ian speaks in more depth with the Chiodo Brothers, the genius stop-motion animators behind the creatures and effects in films like Killer Klowns from Outer Space, Critters, Elf, Team America: World Police, and The Simpsons. Charles, Stephen, and Edward Chiodo discuss their roles in the stop-motion process, how they got into the business, and upcoming projects like Channel 8 from Outer Space, a web series made up of different alien TV shows being broadcast down to Earth.
