And not to rain on any parades here, but Nintendo sees the movies as more of a brand awareness tool, and considers their core business to be gaming fully, still. Mario Kart 8 alone is going to outgross what Avengers Endgame ended up making at the box office by the time everything is said and done, so gaming is still the more lucrative business.

The hope is that these movies are going to keep these games in the consumer market's mind, as well as helping Nintendo with their push into the amusement park sector.

Edit: Nintendo sees gaming as their bread and butter, but as Miyamoto stated a few years ago, they want Mario to be an entertainment icon, bigger than Mickey, not just a video-game icon.
