Corrected entry: Despite its massive global popularity, this is only the second feature-length film based on a Nintendo property. The failure of the 1993 live action film made Nintendo reluctant to license their characters moving forward.

Correction: Pokémon is Nintendo's property. There's been a lot of feature length films in that series, including the live action "Detective Pickachu." Not to mention "feature length film" doesn't exclude made for TV or direct to video films, or even foreign films. One could say Donkey Kong, Kirby, and Animal Crossing had feature length films after 1996. Not to mention there was a 1986 Super Mario Bros. Film.
