Having passed these tests, Arthur prepares to see the Minimoys to celebrate, until his father decides to take him and his mother back to the metropolis.
He then learns that Selenia is held by Maltazard, who is inspired to invade the human world by increasing his own size.
The telescope itself is destroyed in the process, leaving Arthur trapped at his Minimoy size, while Maltazard is free to roam the world.
It was therefore essential to advance the universe: “This is what was done with the Harry Potter saga, and I find it very intelligent: to attach ourselves to a character who grows at the same time as his audience.
Likewise on the French side for Maltazard, the voice is taken over by Gérard Darmon after the death of Alain Bashung.
Luc Besson and production designer Hugues Tissandier created settings that did not appear in the first film: a church, shops, a supermarket, a garage, a hardware store, a police station, a cinema and a fountain, etc.
Also, neither of the American actors that re-dubbed the original dialogues in Minimoys would repeat this due to Weinstein not partaking any distribution of the Arthur sequels.
