The independent film Halloween, which played over the course of fall 1978 through fall 1979 and relied almost completely on word-of-mouth as marketing, was also a sleeper hit, having a box-office take of $70 million on a budget of only $325,000. Its success caused other slasher films to try the same approach, although few fared as well since horror films heavily rely on opening weekend box-office and quickly fall from theaters. Other notable examples of horror sleeper-hits to follow in Halloween's wake include Friday the 13th in 1980, The Evil Dead in 1981, A Nightmare on Elm Street in 1984, Scream in 1996, I Know What You Did Last Summer in 1997, The Blair Witch Project in 1999, Final Destination in 2000, Saw in 2004, Hostel in 2005, Paranormal Activity in 2007, both The Purge and The Conjuring in 2013, and both Happy Death Day and Get Out in 2017.[5]
