As far as I can tell, “Happy Together”’s use in the first Detective Pikachu trailer wasn’t because of any super-specific lyrical parallel with the plot of the film. Sure, Tim whips out his phone a few times, and occasionally acts a little crazy, but really, it seems like the song was meant to highlight the “buddy cop” aspect of the movie, and perhaps to suggest that Tim and Detective Pikachu might have wound up with each other for a reason. Musically, the song’s melancholic verses and incredibly bright chorus parallel the film’s “darker but not too dark” tone and to a certain extent, the personalities of the main characters, with Tim being more low-key and Detective Pikachu more energetic. With all that said, however, I’d be remiss if I didn’t mention that this isn’t the first time the song has come into Pokémon’s orbit-fans of the original N64 Smash Bros. will remember that ads for that game also used this tune, adding another level of nostalgia to the mix. Anyway, do you have your own thoughts on any of this? Feel free to let us know. Thanks.
