Cannibal Holocaust
Italian film, produced in 1980, by Rogerio Diodato
Is one of the most controversial films in history, followed by some of the strangest stories ever, one of which is:

On February 17, 1980, 10 days after the film was shown in Milan
The Italian court issued a decision to arrest the director of the film, and charged with killing the actors in front of the camera!
This film was so realistic that the court was convinced that some of the murder scenes in the film were real and not just representation, and that the director was the one who committed it
Now the director faces a life sentence
Of course the court could have contacted the representatives and made sure they were still alive
But here comes the strangest part of this story
It turned out that the director of the film "Rogerio Diodato" forced the actors to sign a contract that requires them to disappear from view for a full year of the film, in order to maintain the illusion that they actually died in the film
When he found himself threatened with imprisonment, he called the representatives and asked them to come to court to prove they were still alive

This film was banned from the show in 50 countries
On the other hand, he achieved great success in Japan, and was popularly popular
