Joe Otterson TV Reporter Mary Elizabeth Winstead has signed on to star opposite Ewan McGregor in the upcoming Showtime & Paramount+ series “A Gentleman in Moscow,” Variety has learned exclusively. McGregor was first reported to be starring in the show back in August 2022. It is an adaptation of the Amor Towles novel of the same name. Production on the limited series is now underway. It will debut on Showtime in the U.S. and on Paramount+ in additional markets around the world. Per the official logline, the series “follows Count Alexander Rostov (McGregor) who, in the aftermath of the Russian Revolution, finds that his gilded past places him on the wrong side of history. Spared immediate execution, he is banished by a Soviet tribunal to an attic room in the opulent Hotel Metropol, threatened with death if he ever sets foot outside again. As the years pass and some of the most tumultuous decades in Russian history unfold outside the hotel’s doors, Rostov’s reduced circumstances provide him entry into a much larger world of emotional discovery. As he builds a new life within the walls of the hotel, he discovers the true value of friendship, family and love.”
