Okay, so I'm roughly halfway through reading this script, and it's a bit of a mixed bag so far, but... dagnabbit, why didn't “MICHAEL CLAYTON 2: THIS TIME IT’S LESS COMPLICATED AND HAS MORE ACTION" make it into the final cut?
EDIT: Okay, so finished reading it, and that was VERY mediocre overall. I can certainly see why Frank Oz turned it down. I was about to make a looooooong rant about everything wrong about this first draft, but... meh, there's no point, the problems are obvious (the Muppets being out of character, the lack of any real emotional weight, Gary and Mary being bland as ****, referring to the Muppets as bloody PUPPETS. SEVERAL TIMES. WHAT), and the vast, vast majority of the first draft's flaws were evidently ironed out in future redrafts before the final version of the film - which I now admire, and am glad we have, more than ever before.
Still, some jokes in this first draft were funny and I wish they were left in, it would have been nice to get a full rendition of Together Again in the final film, and pretty much every character outside of Kermit, Piggy, Fozzie, Scooter, Walter and Animal seemed to have more to do in this script. But most of those small advantages the first draft has over the final are trivial, fan pleasing stuff anyway.
But yeah. So so so so so so so glad the script went through plenty of alterations before the final product began shooting.
