South Park scribes Trey Parker and Matt Stone are developing a big-screen comedy for Paramount that will feature an all-marionette cast, Variety reports. Described as a spoof of action films, Team America centers around a prototypical action hero who leads the charge to fight the world's evil forces. "We hate those actors who take themselves so seriously and think they are a productive and important part of society," Parker says. "The subtle joke here is that all actors are puppets."
