A Pokemon expert was on-set every day for Detective Pikachu

The entire team behind Detective Pikachu wanted to make sure the movie made fans happy. Obviously Pokemon Co. wanted that as well. That's why during the film's creation, a Pokemon expert was on-set at all times. Lucy actress Kathryn Newton went into detail on the matter.

“Every day on set, there was a Pokemon expert. Every day, making sure we didn’t mess up. One time, I called Bulbasaur ‘he’ in a scene, and he [the Pokémon expert] said, ‘Actually, you can’t call him a ‘he.’ He’s ‘it.’ Genderless. Psyduck is a he. So, there are these really specific things that we cared about, and we hoped that Pokémon experts and just fans [care, too].”
