Larroquette, who recently appeared Off-Broadway in Oliver Parker!, will play Ted Carver, the tough Deputy Chief of Manhattan Borough Detectives, who will likely lock horns with Mac Taylor (Gary Sinise) when the city appears to be terrorized by a sniper.
Larroquette, best known for his work on the sitcom "Night Court," has also appeared on "Boston Legal," "The Practice" and "The John Larroquette Show," among many other screen credits.
