Released in 1999, The Blair Witch Project quickly became one of the most profitable independent films of all time. It wasn’t technically the first found footage horror film, but it’s still the most famous of the bunch. Everyone knows the Blair Witch name (and the names Heather, Josh and Mike), but did you know that directors Eduardo Sanchez and Daniel Myrick’s wildly successful horror flick didn’t even have a script? That’s just one of the facts featured in the last episode of You Think You Know Movies!

Sanchez and Myrick met in college and came up with the idea for The Blair Witch Project back in 1993. They were inspired by old documentaries about occult and paranormal phenomena, which they believed were scarier than fictional horror movies. The Blair Witch Project was filmed over the course of eight days, with the actors improvising their lines based on a 35-page outline and notes that were hidden by the directors throughout the production.
