While many were blacklisted just for supporting left-wing causes, Bernstein actually was a member of the American Communist party and remained so until 1956.
Bernstein received an Academy Award nomination in 1977 and a Writers Guild of America prize for best screen drama.
Bernstein would remember his decision with “relief” over no longer abiding Soviet dogma and “sadness” for the people who were fellow idealists.
The blacklist began to weaken in the late 1950s and ended for Bernstein in 1959 with That Kind of Woman, starring Sophia Loren.
