is crushed by a falling basketball backboard and Carrie's principal and teacher are electrocuted, setting the gym on fire. Carrie exits the gym and seals the doors behind her, trapping staff and classmates. As Carrie walks home, Chris and Billy attempt to run her over with Billy's car but Carrie causes their car to overturn and explode, killing them. After Carrie bathes herself at home, Margaret reveals that Carrie was conceived when her husband was drunk, an act that Margaret shamefully admits she enjoyed. She comforts Carrie, and then stabs her in the back with a kitchen knife and begins chasing her through the house. Carrie levitates several sharp implements and sends them flying toward Margaret, crucifying her; then, she destroys the house and perishes. Some time later, Sue, the only survivor of the prom, has a nightmare in which she goes to lay flowers on the charred remains of Carrie's home, upon which stands a "For Sale" sign vandalized in black paint with the words: "Carrie White burns in Hell!". Suddenly, Carrie's bloody arm reaches from beneath the rubble and grabs Sue's forearm. Sue wakes up screaming and writhing in terror as her mother tries to comfort her. Cast Production DevelopmentCarrie was the first Stephen King novel to be published and the first to be adapted into a feature film. During an interview in 2010, King said he was 26 years old at the time and was paid just $2,500 for the film rights, but added that he was fortunate to happen to his first book. De Palma told Cinefantastique in an interview in 1977: Lawrence D. Cohen was hired as the screenwriter, and produced the first draft, which had closely followed the novel's intentions. United Artists accepted the second draft but only allocated De Palma a budget of $1.6 million, a small amount considering the popularity of horror films at the time. The budget eventually rose to $1.8 million. Certain scripted scenes were omitted from the final version, mainly due to financial limitations. Casting Many young actresses auditioned for the lead role, including Melanie Griffith. Sissy Spacek was persuaded by husband Jack Fisk to audition for the title role. Fisk then convinced De Palma to let her audition, and she read for all of the parts. De Palma's first choice for the role of Carrie was Betsy Slade, who received good notices for her role in the film
