I kept wanting to wait but it seems that either their trip is days-long or they just gave up. On a website called reddit, the film creators link, and they would answer. The way reddit works, it can be difficult to find their answers among all the unanswered questions. So, I decided to be a ~great person~ (lol) and compiled them all. Some appear to restatements of stuff you've probably seen before, but of these responses are interesting.
The people answering the questions were Chris Williams, Don Hall, Roy Conli, and Paul Briggs -- the directors, producer, and head of story, respectively.
