The Shining
Shelley Duvall was crying so hard during the filming of The Shining that she ran out of tears. She had to drink water constantly to stay hydrated.
The Thing
In this film there are no female characters, and the only references to women are the voice of the chess computer and the participants in the game. Only one staff member was female, but she had to leave because of her pregnancy and was replaced by a man.
Candyman
Tony Todd really had to put bees in his mouth with just a protector so they would not go down to his throat. Acting is not an easy job and less under those conditions.
The Exorcist
During the filming, the room had to remain at a very low temperature so that the frozen breath was real. Linda Blair wore only a nightgown so it was very cold, and to this day can not stand the low temperatures.
Paranormal activity
It is said that the actors were not given a script, but ideas about how they should behave. Steven Spielberg is a fan of this movie, but could not see it during the night due to fear.
Child’s Play
The film had many negative critics for its violence and everything worsened when a band of adolescents killed a girl of 16 years. While being tortured they made him listen to recordings where the leader called himself Chucky.
Final Destination 3
To perform the premonition scene, the actors had to ride the roller coaster 26 times. Probably, he was no longer afraid of them.
Poltergeist
Many believe the film is damn because several of the actors died young. Heather O'Rourke, the adorable little girl, died at age 12 and Dominique Dunne at age 22. On the other hand, Will Sampson died in surgery and Julian Beck of cancer.
