The fabulous Ellen Burstyn had to perform a very risky scene while filming The Exorcist. Director William Friedkin instructed a stuntman to yank Ellen on a wire, with the intention of making the scene look as real as possible. When the actress told Friedkin she was afraid of getting seriously hurt, he instructed the stuntman not to pull her so hard - then he went behind her back and told him "give it to her." The result: Burstyn was pulled so hard that she ended up flying across the room and landing on her coccyx. She was so furious -as it can be seen on the film- not only because Friedkin didn't care about her fear, but also because he actually wanted to get a quick shot of it before calling an ambulance
