By its very nature, horror is designed to disturb, provoke, and scare its audience. As such, it comes as little surprise that horror has traditionally been the genre associated withthe scariest movies of all time. However, cinema has played host to a number of offerings from outside the genre that are just as terrifying as the scariest horror film, if not more so. While film fans may primarily look to thebest horror movies of all timefor their cinematic scares, a film’s ability to terrify its audience is by no means limited to one genre.
This status quo is only compounded when the movie draws inspiration froman unbelievable true story. The fact that the horrific events being depicted by the movie in question are based in reality lends an eerie air of authenticity to proceedings, one that emphasizes the worst aspects that the human experience has to offer in unflinching clarity. As such, there’s a unique brand of fear associated withterrifying non-horror movies that are based on a true story,from tales of attacks by wild animals, to alleged accounts of alien abduction.
