Horror movies are known for pushing boundaries. Viewers enjoy them for their scares, gore, and suspense. Inevitably, most of these movies offend certain audiences. But a select few were so grotesque or horrific that governments heavily restricted or even completely banned them. Sometimes the concern was extreme violence or graphic sexual scenes. In other cases, fears about copycat crimes led to them being pulled. These controversies helped them become some of the most infamous horror movies ever made.
1. The Exorcist (1973)

Synopsis:
William Friedkin’s 70s classic depicts a young girl who becomes possessed by a demonic entity. A desperate mother seeks the help of the Catholic Church, leading to an exorcism performed by two priests.

What Was Banned:
The Exorcist faced bans or severe restrictions in several countries, including Singapore and parts of the United Kingdom. In the UK, distributors refused to be involved with the controversial project, and it was unavailable on home video for years. In America, while not banned, young people in Catholic school were told not to see the film, as it would open them to demonic possession themselves. Reports of audience members fainting in theatres were widely talked about.
2. Cannibal Holocaust (1980)

Synopsis:
Presented as a recovered documentary, this was one of the earliest “found footage” movies before they became hip.

Tobe Hooper’s famous slasher focuses on a group of friends who accidentally stumble across a deranged family. The craziest of the bunch is the chainsaw-wielding Leatherface.
