Carrie was a terrific piece of work. At the end of the movie comes, when Amy Irving kneels down to put the flowers on Carrie's grave, a hand comes up through the grave and seizes her by the arm. The audience went to the roof, totally to the roof. It was just the most amazing reaction. And I thought, 'We have a monster hit on our hands. Brian De Palma has done something new. He's actually created a shock ending that shocks an audience that was ready for a horror film.' And there were several people who did it after that.
