He also appeared in the anti-war musical "Johnny Johnson", Sidney Kingsley's "Men in White", the Elia Kazan-directed "Thunder Rock", "My Sister Eileen", and "Cafe Crown". Writing about the Group's production of "Awake and Sing!", the "New York Times" critic Brooks Atkinson said, "...Morris Carnovsky as the lonely old sage struggling with ideas he cannot resolve or use, gives a performance worth a mayor's reception on the steps of City Hall. Probably Mr. Carnovsky and Mr. Adler would have become remarkable actors in any case. But the discipline of the Group Theatre has given them a mastery of acting they could never have achieved by themselves. The Group Theatre makes good!"
