World for Ransom is an unofficial extension of the popular 1950s TV series China Smith. Most of the Smith personnel, including star Dan Duryea, director Robert Aldrich and cinematographer Joseph Biroc, are on hand for this inexpensive but well-mounted melodrama. Duryea plays a mercenary adventurer who gets mixed up in a scheme by foreign spies (who wear baggy suits and speak with Slavic accents) to kidnap a nuclear scientist. Actually it isn't the whole world that's held for ransom--only the city of Singapore, which the spies threaten with nuclear annihilation. World for Ransom star Dan Duryea is solidly supported by old pros Gene Lockhart, Patric Knowles, Reginald Denny and Nigel Bruce.
