(Contains very mild spoilers for
Muppets Most Wanted; nothing you wouldn't pick up from the basics of the pre-publicity so far.)
So I've just learnt that back when
The Muppets was still a vague idea Jason Segel had for a film called
The Greatest Muppet Movie Of All Time!, Ain't It Cool got hold of
a script. And one of the concepts that didn't make it into the film we eventually saw was "Ms. Piggy ends up in jail. In the cell next to her is Charles Grodin, still incarcerated after The Great Muppet Caper."
Now I can think of two reasons that scene didn't make it in. 1) The whole "Piggy in jail" storyline, whatever it involved, was apparently abandoned and 2) Nicky Holiday was arrested in London, so why would he be in jail in Hollywood? (Or Paris, if this scene was before they got the gang back together.)
Muppets Most Wanted is going to be set in London. And it involves Kermit being mistaken for a criminal.
Hmmm...
