Asking for a friend… 
Just kidding. I have the scripts for the original 78 film, H18 and HKills. I’d love to complete the collection, but somehow I don’t think this is one script that we’re gonna see any time soon.
I take it that’s a no then?
I’ve searched the most reliable sources for movie scripts, and sadly no it hasn’t been released. Usually they get released without being leaked eventually, just a waiting game.
