But the movies never mention anime locations(outside of the actual region and pallet town I believe)
That is an anime only location, meaning without the anime, Ash wouldn't even know about the valley. That seems enough to confirm it for me.
That logic is b/s.
Sorry but you're assuming that anime only locations are never, or never will be mentioned in the movies.
Regardless, Orange Islands is mentioned in Movie 2 and Characific Valley is mentioned in Movie 3.
