three Communist-front organizations. Firstly, he was an executive board member of the Actors' Laboratory Theatre, which the Committee did not find was Communist in itself but rather its board of directors was made up almost exclusively of known Communists Party members or Communist sympathizers, including Dassin. Secondly, he had been a member of the Artists' Front to Win the War gathering on October 16, 1942, which the Committee on Un-American Activities cited as subversive. Thirdly, he was a sponsor of the National Council of the Arts, Sciences and Professions' Scientific and Cultural Conference for World Peace, held from March 25–27, 1949, and which the Committee on Un-American Activities also cited as subversive.

Dassin was however replaced by Richard Sale after pressure from Hollywood politics. On April 25, 1951, film director Edward Dmytryk, one of the "Hollywood Ten" who had been blacklisted in 1947 after refusing to testify, gave a wilful and revised testimony to the House Committee on Un-American Activities. In his revised testimony, Dmyrtyk revealed that the Screen Directors' Guild included seven known Communists. That was one of the first times that the Un-American Activities Committee heard of film directors being Communists, because it had previously concentrated on screenwriters in the Screen Writers' Guild. Dassin was named as one of the seven directors, along with Frank Tuttle, Herbert Biberman, John Berry, Bernard Vorhaus and Dmytryk himself, who were present at a Communist meeting at Berry's house, for the purpose of electing
