Fall TV preview: CSI

Season 11 picks up where the show left off last spring, with Dr. Ray Langston (Laurence Fishburne) in a pool of blood after being stabbed by ”Dick & Jane” serial killer Nate Haskell (Bill Irwin). We’re guessing he’s fine, so let’s move on to bigger news: Justin Bieber makes his acting debut in the season premiere! He will play a kid who belongs to ”a group who believe that our country has been co-opted by profiteers,” says exec producer Carol Mendelsohn. (Bieber will also make an appearance during February sweeps.) Also look for a new love interest for Catherine (Marg Helgenberger, who maintains this will be her final year on the hit). ”It is a transitional year for Catherine,” says Mendelsohn, holding out hope that her star will reconsider. ”It could be a way to end things for her — or to begin things.” SEPT. 23
