Hell House LLC

In this found-footage gem, a documentary crew visit the site of a haunted house attraction whose opening night ended with 15 unexplained deaths. Eventually the crew come across a surviving employee who has footage that shines a scary light on what really went down that night. As we watch those ill-fated thrillseekers shuffling through the horror house, the knowledge of what's about to happen makes for a squirm-and-scream-inducing good time. Dread Central called it "a perfect fright flick for the Halloween season" which features "one of the creepiest clowns to appear in a horror movie in a long time." Sorry Pennywise!
