For a lot of people, Sam Waterston is the face of angry lawyering on TV, thanks to the 16 years (368 episodes!) he spent as quick-witted, sarcastic, occasionally furious district attorney Jack McCoy on the long-running Law & Order franchise. (Meanwhile, Michael Moriarty fans are forced to simply pick up the scraps whenever older episodes of the show get re-run on A&E.) Now Waterston is bringing Jack back, with Variety reporting that McCoy is set to appear as a guest star in an upcoming episode of NBC’s functionally unkillable Law & Order: SVU.
