Trivia, insights & behind the scenes
Shot during actual escalation of US involvement in Vietnam, making its arms-dealer villainy hit different. Studio Toho basically made anti-war propaganda disguised as spy thriller.
Jerry Itō, who plays the villainous American Rudolf Kent, was actually born in NYC and became Toho's go-to 'foreign face'—his awkward Japanese delivery was genuine, not acting.
