For a dozen years during the Cold War, accused members and former members of the American Communist Party were barred from working in the movie industry. The blacklist era ended when Kirk Douglas gave screenwriting credit to Dalton Trumbo — probably the most famous of the Hollywood 10 — for his work on "Spartacus." The movie, which starred Douglas and was executive produced by him, opened 48 years ago this week. On Oct. 22, the 91-year-old actor will be honored at the Ambassadors for Humanity Gala Dinner benefiting the USC Shoah Foundation Institute. Douglas, who had a stroke 12 years ago that has impaired his speech, discussed the legacy of "Spartacus" and of the contemporary political climate in Hollywood.
