Trivia: The movie came about partially thanks to the "Super Nintendo World" theme parks. As the Nintendo World parks were to be situated in Universal Studios theme parks, Mario creator Shigeru Miyamoto met many Universal executives, including Illumination CEO Chris Meledandri, to discuss the park's creation. Miyamoto felt Meledandri was a kindred spirit due to their similar creative processes and began talking with him about making a new Mario movie. Within a few years, the project was greenlit.
