The World Before the End script was created as a distraction and part of my brainstorm process while writing my main script. It stemmed from a short story idea that I had on my (now non-active) tumblr site.
From that it evolved into the sketches and expanded into the script.
The “poster” was created as a mock up of how a teaser should be and it further helped in the process.
The script can be read of course…one simply has to ask :).
