On a technicality... MTM was redoing TMM, if in reverse. The whole trying to make it in the entertainment business... only with a big break up instead of everyone meeting each other. There are only so many plots out there, and there is no such thing as an entirely original idea that isn't batcrackers insane. I dunno about you, but I don't want to see a movie that's about a glasses case vomiting out staplers until the film slowly deteriorates and turns into a walrus. Every basic outline of a plot has been done before. No matter how different from GMC they make the film, it's still a film where the Muppets face off against a bad guy and rise up victoriously. And frankly, that's not just every Muppet Movie plot, that's like more than half of the plots of everything out there. The Muppets had a LOT of coincidentally similar threads to VMX. Some of it is eerily similar (referencing Kung Fu films, albeit in completely different ways), but some of it just manages to be similar because of the similar trope of some bad guy wanting something the good guys had... in both cases, Muppet real estate. Even if Stoller, Bobin, and Segal have never EVER seen VMX and were unaware of its existence, they couldn't help having the same exact sort of antagonist and plot in a movie because it's an old stand by. Unless they willfully copy GMC, or make an indirect sequel based on Nicky Holiday getting out of prison and wanting revenge on the Muppets, I don't think this could be a direct remake or direct copy of any kind, other than the fact that certain kinds of plot points will have similar threads to them... but then again, on a technicality, all Muppet Movies have that same thread to them.
