Barrett wasn't going to touch my extraterrestrial theory with a 10ft tree branch, but he did remind me that, in the 1999 movie, Heather, Michael, and Josh do wake up one morning to find blue slime on Josh's bag. Intriguing. What he did say, and what's clear from his movie, is a love for homegrown legends and the potential density of made-up mythology.
"I love going back to the early periods of America and how horrifying life was back then. That era of Puritanism and genocide of the Native American population is such a fascinatingly horrific time. There's a lot to play with there." Pile that lore into a few acres of woods and you get Blair Witch, a reinvented horror franchise that gives 21st-century folk panic attacks (or was that just me?). "I grew up in the middle of Missouri, gotten a little disoriented before, there's a terror of, 'Wait, where's the trail? I could die so easily.' Especially now, we're so reliant on technology that a fear of nature is even more subconsciously horrifying."
