Yeah, that was a lil joke Tom sent to Zach. Coz Tom & Zach get these scripts sent to them all the time asking these cats to read 'em & give notes. I guess these senders don't realize that it takes a good 6-8hrs to properly read/ give notes. (This is one of the reasons Tom's so burnt out-so many people askin for favors that are pretty elaborate)
So when you send yr script to these guys, you are basically asking them a huge huge favor---& they're busy, may not have time etc.
ANYWAY, Tom sent a giant--double the size of most movie scripts-- blank script about the size of a telephone book, with just a title page and one page of (really BADLY WRITTEN) movie script for his "movie" project -The Invisible Dude.
I'm guessing Zach was like "WhattheFunyons??!?! Jeezus lookit this feckin humongus thing i gotta read that Scharpling sent" when he got it!
