The production team went to Dubai as location scouting for the setting of the movie, Dahara City.
This movie features eleven Legendary Pokémon, more than any other so far.
This is the only movie in Pokémon the Series: XY to not feature a human antagonist.
This was the first movie to not have Hideki Sonoda act as screenwriter since Pokémon 4ever : Celebi, la voix de la forêt (2001). Instead, it was written by Atsuhiro Tomioka.
