Cursed production

Many of 'The Exorcist' cast believed the movie was cursed due to the many mysterious events that occurred in and around production.

Filming had to be delayed because the set for the family house had burned down. Then, Ellen Burstyn - who plays Regan's mother Chris - was injured by a harness during a scene where she is thrown backwards by the demon.

Tragically, the picture was also plagued with deaths. Actors Jack MacGowran and Vasiliki Maliaros passed away shortly before the movie premiered. Jack died from the flu in 1973, and Vasiliki of natural causes.

As well as this, both Linda Blair's grandfather and Max Von Sydow's brother passed away during production.
