Location footage in late-1960s Hong Kong highlights this espionage yarn with sci-fi overtones in which scientist Gregory Peck is persuaded to go to China in search of a revolutionary crop additive that can prevent famine. The technological gimmick has Peck outfitted with a tiny radio that allows him to be a mobile human bug and transmit everything he hears to an intelligence arm of the CIA and MI6 based in London. The movie feels like a big-budget version of a "Time Tunnel" episode -- minus the time travel.
I've always thought that this film inspired the short-lived NBC series "Search."
