'Most disturbing film' banned in six countries was so horrific actors couldn't finish their lines

A movie branded the 'most disturbing film' was so horrific that actors involved could barely finish their lines.

Salò, or the 120 Days of Sodom, which was created in 1975 by Pier Paulo Pasolini, has been described as one of the most disturbing films of all time.

And when you learn what it's about, you can see why.

The film focuses on four Italian men who kidnap nine teenage boys and nine teenage girls.

They lock them in a huge house and torture them for months, conducting utterly heinous and gruesome acts, including extreme graphic violence and rape.

The film is based on the book by Marquis de Sade, which he wrote while imprisoned in 1785.

Upon its release, the movie was banned in Italy, Finland, Australia, West Germany, New Zealand and Norway.

People have been discussing the movie on social media and Reddit, where one person described it as the 'most f****d movie' they had seen.

"I wanna say thanks for sharing? But this was honestly the most f****d movie I’ve ever seen," they wrote.

While another added: "There's something seriously wrong with you then cause this is clearly an extremely disturbing film.

"You have to be a 100% psychopath to not be at least a little scarred or disturbed by this."

And a third added: "Literally such a disgusting movie like what was the point of it."

According to a Wikipedia claim, the movie was shot without any sound, meaning all dialogue would be dubbed after filming.

However, due to all the controversy, the actors in the film didn't return and so they had to be dubbed by other actors.

Over the years, a number of disturbing films have been banned across the world.

One movie, Nekromantik, was a 1987 German horror flick that was hugely controversial at the time it was released, due to its sickening subject matter.

It tells the story of Robert, a street sweeper who likes to have sex with corpses.

The movie, which starred Bernd Daktari Lorenz as Robert and Beatrice Manowski as his wife Betty - is seriously dark, so it's no wonder that it was banned in several countries, including Iceland, Malaysia, Singapore, certain provinces in Canada, Australia and Finland.

On one occasion, Robert is involved in recovering the body of a man, who had been discovered in a lake.

He manages to secretly take the man's body home for Betty and the pair carry out their disturbing fantasies.

Robert ends up getting fired from his job, dumped by Betty and taking his own life after committing two, gruesome murders.

One wrote on Reddit: "I think this is the only horror movie I can remember that I regret seeing. It revolves around necrophilia and is basically soft-core necrophilia porn."
