Trivia / The Secret of the Magic Potion

• Celebrity Voice Actor: In Brazil, Asterix is voiced by Gregorio Duvivier of BackDoor fame, who also qualified as a Promoted Fanboy.
• The Other Darrin:
  • A rather unusual case for Asterix himself since it also happens to involve Role Reprise. This is the first animated Asterix film in which Roger Carel didn't do the voice acting for the title character, as he had retired back then — he has voiced Asterix since Asterix the Gaul all the way back in 1967 up until Asterix: The Mansions of the Gods in 2014, and he passed away in 2020. Asterix was voiced instead by Christian Clavier, the actor who played him in live-action in Asterix & Obelix Take on Caesar and Asterix & Obelix: Mission Cleopatra.
  • In this film, Dogmatix is voiced by an uncredited voice actor.
  • In the English version, Cacofonix is voiced by Andrew Cownden in place of Alan D. Mariott from The Mansions of the Gods.
• Posthumous Credit: Morten Røhrt, who did the voice of Julius Caesar in the Norwegian dub, died a few weeks before its release in Norway.
• Production Posse: Just like Asterix: The Mansions of the Gods, a good deal of voice actors of the French version (Lionnel Astier, Franck Pitiot and others) also worked in Kaamelott, by director Alexandre Astier. This also includes Christian Clavier, who's been one of the guest stars in Kaamelott.
• Role Reprise: Christian Clavier voices Asterix. He played the character in the 1999 and 2002 live-action films.
