The Passenger (Russian: Пассажирка(Passazhirka)) is a 1968 opera by Mieczysław Weinberg to a Russian librettoby Alexander Medvedev. It was premiered by musicians of the Stanislavsky Theatre in the Svetlanov Hall of the Moscow International House of Music on December 25, 2006, in a semi-staging conducted by Wolf Gorelik. The cast included Anastasia Bakastova as Katya, Natalia Muradimova as Marta, Natalia Vladimirskaya as Liza, Alexey Dolgov as Valter and Dmitry Kondratkov as Tadeush.
Medvedev's libretto is based on the 1959 Polish radio play Pasażerka z kabiny 45(Passenger from Cabin Number 45) by concentration-camp survivor Zofia Posmysz. The play was rewritten in 1962 by its author as a novel, Pasażerka. Posmysz also worked with Andrzej Munk on the screenplay for his related, posthumously finished 1963 film Pasażerka. Medvedev's libretto was reworked in 2010 for the first staged performance of the opera at the Bregenzer Festspiele into German, English, Polish, Yiddish, French, Russian and Czech.
