Leopoldstadt has carved a place in history. The show debuted to rave reviews — and a Best New Play Olivier Award — in London’s West End, quickly selling out before moving to the Longacre Theatre on Broadway. The play is by the legendary Tom Stoppard, whose career spans nearly seven decades. New York Theatre Guide’s five-star review hails the show as “first-rate” and “a masterwork” — and it’s perhaps his swan song. Now 85 years old, Stoppard indicated Leopoldstadt might be his final work.
