The Super Mario Galaxy Movie goes beyond the Mushroom Kingdom and introduces a whole new cast of characters. As we now know, there’ll also be some faces that aren’t even from this particular Nintendo universe.

It’s led to discussion once again about a possible “Smash Bros.-style Nintendo Cinematic Universe” movie, so what are the chances of it actually happening?

Polygon asked Shigeru Miyamoto about this recently, and while he’s willing to make exceptions for his beloved Pikmin and some other characters in Mario’s new outing, it doesn’t necessarily mean it’s building up to an all-star event led by the iconic Nintendo mascot:

Shigeru Miyamoto: “I don’t think you’ll have a situation [where] all Nintendo characters would be joining [together in one film]. As you know, my rule is that Pikmin can appear in any [Nintendo] series.”

For now, the focus is on Mario’s universe and rather than opening the door to every Nintendo series, the team simply wants to “spice” things up by including “secret cameos here and there”, so they’ve got characters that slot into Mario’s world, and also fit the Galaxy movie’s space theme.

Illumination’s CEO Chris Meledandri elaborated on Miyamoto’s comments in the same interview, mentioning how the crossovers in the Galaxy movie are more incidental than strategic. According to Meledandri, Nintendo and Illumination focus on the project at hand, and the ideas come about based on what might be fun or may fit a certain scene.

Chris Meledandri: “If we agree that it’s a fun idea, then we look to Miyamoto-san to just make his own judgment about whether or not it feels right to him.”

So, there you go – according to Miyamoto we probably shouldn’t expect a Smash Bros. movie to happen, at least any time soon.
