Trivia / All Hail King Julien

• Acting for Two: Nearly every main actor voices one or more characters. For example, in addition to Clover, India de Beaufort also plays her sister Crimson and their deceased Grandma Rose.
• He Also Did: Writer Sharon Flynn & director Stephen Heneveld would later work together in a similar capacity on Big Hero 6: The Series.
• I Want You to Meet an Old Friend of Mine: Producer Mitch Watson and story editor Michael Ryan were in their respective positions on Scooby-Doo! Mystery Incorporated.
• The Other Darrin:
  • Julien and Maurice retain the same replacement voice actors that they had in The Penguins of Madagascar (Danny Jacobs and Kevin Michael Richardson, respectively).
  • In the European French dub, Mort does not have the same voice as in The Penguins of Madagascar because his actor moved to Canada.
• Refitted for Sequel: Masikura was supposed to play a big part in the first Madagascar film, but all the scenes showing her as a Fortune Teller was cut for time. Instead, she was relegated to a non-speaking role as a stenographer during the "Town Meeting" scene in the airplane.
• Role Reprise:
  • Danny Jacobs, Kevin Michael Richardson, and Andy Richter return to voicing Julien, Maurice, and Mort. The former two are from The Penguins of Madagascar and the video games while the latter is from the movies and cartoons.
  • Alex's cameo in the series finale has Crispin Freeman reprising the role from the second and third Madagascar video games.
• What Could Have Been: The show was originally pitched as a serialized parody of Game of Thrones before being changed to be an episodic comedy. This approach was eventually utilized for the fifth season, Exiled.
  • Mitch Watson originally wanted to cast frequent collaborator Udo Kier as a villain. However, because the actor's thick German accent was difficult to understand, the character had to be recast.
