In 2003, Larroquette reprised his narration for the remake of The Texas Chainsaw Massacre. From 2004 to 2006, he played the title role in the McBride series of American television films. In 2007, he joined the cast of Boston Legal playing Carl Sack, a serious, ethical Lawyer (the polar opposite of his more famous Lawyer character, Dan Fielding). He also guest-starred in the drama House where he played a previously catatonic father awakened to try to save his son, and on Chuck as veteran spy Roan Montgomery. He has also done two voice roles in Phineas and Ferb as Bob Weber, as a lifeguard, as well as a man to marry his wife and the boy's aunt Tiana Weber in another episode. Most recently, Larroquette has been seen as a regular on The Librarians as Jenkins (actually the long-lived Camelot knight Sir Galahad), who provides support to the Librarians as a researcher and caretaker.
