Sam Waterston by Eric Liebowitz/NBC
Sam Waterston has officially been "promoted" to New York District Attorney on Law & Order, as longtime prosecutor Jack McCoy fills the vacancy dictated by possible presidential candidate Fred Thompson's exit from the role of Arthur Branch. Though he may, as a result, see less screen time, Waterson puts the best spin on the sitch, saying that while the career move is "a logical step" for McCoy, "politics isn't his game." As such, "There'll be fireworks," the actor predicts. "I'm looking forward to it."
