The relatively relaxed movie censorship in the postwar years enabled Columbia to produce To the Ends of the Earth, a film which dealt with the previously taboo subject of drug smuggling. T-man Dick Powell is sent to several foreign locales to track down an Opium ring. The villains are subversives (Red? Fascist?) who plan to take over the world by hooking everyone on the "hard stuff." The film is chock full of mysterious European and Oriental types like Vladimir Sokoloff, Ludwig Donath and Fritz Leiber; even leading lady Signe Hasso speaks with an accent, which in 1948 was enough to immediately put her under suspicion. Lending credence to this sprawling adventure yarn is the presence of several actual treasury agents in bit parts, including commissioner Harry J. Anslinger.
