- Hey, It's That Sound!: Listen to Palkia closely and you'll recognize the two roars used for its roar: Boga the varactyl from Revenge of the Sith, and Heisei-era King Ghidorah.
- Milestone Celebration:
- Subtle, but the theatrical debut releases special trading cards related to the previous nine movies.
- Less subtly, the Pokémon shown at the beginning are actually the focus Pokémon from every previous movie, in order. This is why Unown and Lucario are present.
- Missing Trailer Scene: As usual for these movies. In this case, there was a scene of Ash riding his Pidgeot.
