how do people know the ending of the half of it already?? was the script leaked or smth

And another anon:

Hey, I was wondering where the supposed “leak” of the half of it is? I would like to read it

A whiiiile back it was up on reddit (and probably other places?), I found out through this post which summarizes much of it:

It’s been removed since but it should be reinforced that we have no idea what the actual ending or even movie itself are like now, anything could have changed from that script to actually being shot. For what it’s worth, the ending as it was written was open-ended but hopeful for the f/f pair.
