Театр имени Моссовета
During the Great Patriotic War Plyatt stayed in the sieged Moscow, gave theatre performances and worked as a radio host, regularly crossing the city during heavy bombings. In 1943 he moved to the Mossovet Theatre where he had served for the rest of his life. He was known for his long-lasting friendship with Faina Ranevskaya, and they regularly performed together in both plays and movies. They appeared in two leading roles in the popular "The Rest Is Silence" play, the Mossovet stage adaptation of "Make Way for Tomorrow" where Ranevskaya performed till the end of her career; Plyatt's Barkley Cooper is universally praised as the peak of his acting skills.
