The initial hardboiled theme later evolved to include intellectual elements involving action, and occasionally with comical elements as well. Tetsuro Tamba starred in the 1967 film You Only Live Twice as Japanese Secret Service agent Tiger Tanaka, an ally of James Bond. This role greatly influenced his image in "Key Hunter".
