Re: Frozen in Kingdom Hearts 3
From a thematic standpoint, I think it'd fit in perfectly. The film's two main characters, Elsa & Anna, have quite a few things in common with Riku & Sora when it comes to trust, fear, and bringing people home.
From a business standpoint, Kingdom Hearts has everything to gain from Frozen. Even if it is a few years after the film's release, it'll still be fresh on people's mind and all of the praise it has been getting can easily be referenced when Kingdom Hearts is being promoted.
I should probably watch Wreck it Ralph, from what I understand part of that movie's charm is that it's a bit meta and has a lot of cultural references? You think that type of style would fit in with Kingdom Hearts?
Well, Tron was rather meta and it made it into KH2 & KH3D. The idea that the inhabitants of a world recognize they might not be "real" in the context that they are just zeros and ones has even been visited by Re:coded, so...it's certainly not out-of-bounds in that regard. The cultural references, mainly the video game ones, probably wouldn't make it into KH if they made it a world.
You'd need to see the movie to understand what I mean with my statement, but the bulk of the story happens in one specific "game" and the rest serve more as world-building and plot setup. It wouldn't be too hard to work it into Kingdom Hearts. Stranger things have happened...
I don't doubt however that Disney will be quick to merchandise the hell out of Frozen if it becomes a commercial success, it has that whole Disney princess appeal.
Oh Jeels, Disney merchandised Frozen before Frozen was even close to coming out. There were more toys and picture books out than trailers before November even rolled around. xD
