A bit of fact and a bit of speculation with the upcoming Detective Pikachu movie. First up well discuss the fact. A trailer for Detective Pikachu has just received a rating, which indeed means a trailer will be launching soon. Now for the speculation side of things. Warner Bros. is bringing Fantastic Beasts: The Crimes of Grindelwald to theaters next week, and they're also the distributor for Detective Pikachu. It seems pretty damn likely they'll play the Detective Pikachu trailer before Fantastic Beasts: The Crimes of Grindelwald.
