The exec producer behind CSI wants to break into the reality scene. As reported in the current issue of TV Guide magazine (on sale now), Anthony Zuiker is developing a hip-hop version of American Idol titled Ruckus. "It incorporates DJ, MC rap, breakdancing and graffiti," he says. "I'm running around town pitching it right now." CBS officially passed on the project, but Eye network prez Les Moonves wants to keep Ruckus in the Viacom family. Says the exec: "I'm thinking about it for [sister network] UPN."
