The Film
- Banned in China: In what should really be no surprise, the movie was banned in Greece until the junta was overthrown in 1974.
- Cast the Expert: The doctors were played by physicians at the hospital where they were filming.
- Completely Different Title:
- Taiwan: Hot News
- Turkey: Immortal
- The Foreign Subtitle:
- Finland: Z: He Lives!
- Hungary: Z, or Anatomy of a Political Murder
- Italy: Z, the Orgy of Power
- Sweden: Z: He's Alive
- No Stunt Double: The low budget meant that the actors had to perform their own stunts.
- Voice-Only Cameo: François Chaumette (who voiced HAL 9000 in French in 2001: A Space Odyssey the previous year) has a small voice role.
