In 1931, he helped found the Group Theatre, which specialized in dramas with socially relevant and politically tinged messages. He later explained: "We founded the Group because we were sick and tired of the old romantic theater and the encrusted star system. We weren't interested in stars. We were looking for real, living drama." Many of the Group's members were inspired by the Moscow Art Theatre and several members, including Carnovsky and his wife Phoebe Brand also joined the American Communist Party. Carnovsky summered at Pine Brook Country Club in Nichols, Connecticut, with the Group Theatre in 1936, as he worked with the Group during all their summer rehearsal periods, most of which were spent in the Catskills and upstate New York.
