Dick Wolf has called problem-plagued Law & Order: Criminal Intent star Vincent D'Onofrio some much-needed backup: The producer has tapped franchise vet Chris Noth (aka Det. Mike Logan) to join Intent as a series regular. D'Onofrio and Noth will split the case loads, with each fronting 11 episodes next season. "The hardest job in show business is being a single lead on an hour drama series," Wolf said in a statement. "Vincent has done an unbelievable job for the last four seasons, but... the grueling pace finally took its toll. This is an ideal solution." How did Angela Lansbury do it all those years?
