The House of the Devil is a 2009 horror film written, directed, and edited by Ti West, starring Jocelin Donahue, Tom Noonan, and Mary Woronov. It combines elements of both the slasher film and haunted house subgenres while using the satanic panic of the 1980s as a central plot element. The film attempts to recreate the 1970s and 1980s style of horror films, using filming techniques and technology similar to those used in that era.
