Zak Bagans, the host of Travel Channel's Ghost Adventures, wrote and directed Demon House, the second film he has made since 2004.

[1] The film is based on the "mass hysteria" which surrounded the 2014 alleged demonic possession in Gary, Indiana of the Ammons family.

[5] Steve Barton of Dread Central said the film was one of the "single most compelling documentaries on the existence of the supernatural that I've ever witnessed".

[6] Noel Murray, writing for the Los Angeles Times said of the film: "Zak Bagans' documentary Demon House is essentially an uncensored, overlong episode of his long-running Travel Channel series Ghost Adventures.

And while this particular 'paranormal investigation' may terrify the more credulous among Bagans' fan base, skeptics are likely to feel bored and confused.
