and I showed him why a woman has to churn her wrist [more than a man does]." As they were arguing about this, a photographer visiting the set was taking pictures of the two of them. When Friedkin saw this, he went over to the photographer, removed their film from the camera, and tore it up, then cleared the set so the two could consider the sensitive discussion privately. Dietz was appreciative of this display of control on his part. "He knew how to create an environment where horror actors would be at their best." "This particular scene is the most thought about and talked about scene for the obvious reason that it programs two things that are generally not programmed up-front in the human mind ... sex and religion", Friedkin said at the time. It lasts only 50 seconds, yet to many viewers seems much longer, he noted.

"I've learned over the years that [it's] the most terrifying scene", Friedkin said in 2015. "​【51 m】Medical science impinging upon the innocence of this little girl. Which is more disturbing than the demon." It has been criticized as "unappetizing", the film's "most needless scene", and "revolting". British comedian Graeme Garden, who has a medical degree, agreed the scene was "genuinely disturbing" in his review for the New Scientist; he called it "the really irresponsible feature of
