Trivia Tropes:
- Approval of God: Albert Uderzo liked the movie, and even preferred it to its follow-up Asterix & Obelix: Mission Cleopatra, which he found too remote from the spirit of his comic books.
- Fake Nationality: German actor Gottfried John as the Roman (not quite Italy yet) Julius Caesar.
- Magnum Opus Dissonance: Albert Uderzo considered the film as the best live action adaptation of his comics. Most people tend to think Asterix & Obelix: Mission Cleopatra is the best.
Other Trivia:
- It was the most expensive French film at the time of its release (275 million francs, about 56 million in 2019 euros).
