During the film’s final scene where Carrie’s bloody arm reached up and grabbed Sue Snell in her dream to pull her down into the grave, Spacek even agreed to be her own stand in. She laid in a small compartment underneath the portion of the set where Amy Irving was, and is indeed her actual arm pulling her down before Irving’s character Sue Snell wakes up screaming and the film ends. Such facts are mere testaments to Spacek’s overall professionalism and work ethic as an actress.
To give this scene more of an eerie feel, Brian DePalma filmed it backwards, then ran it in reverse using slow motion. This effect lends itself to the final scene having a dreamy appearance. A scene that was not included in the book, and has terrified moviegoers. So much that it has been copied by numerous slasher films ever since, including Friday The 13th where Adrienne King’s character is pulled under the canoe by Jason Voorhees. The final scene in Carrie was inspired by the final scene in Deliverance where Ed (played by Jon Voight) wakes from up from a dream where he sees a disembodied hand rising from a lake.
As mentioned before, Carrie also launched the careers of many in the industry who would either become bankable names through box office success, winning or being nominated for Academy Awards, or having long sustaining careers in supporting roles. An accomplishment few films are lucky to even have, and Carrie is now one of the best examples of displaying young artists who would go on to bigger and better things in Hollywood. Careers there were both in front of and behind the camera. A few even fell in love on the set, quite odd for what is considered to be a horror flick.
DePalma was married to Nancy Allen, and she starred in a few of his films after Carrie. Home Movies, Dressed To Kill, and Blow Out. The latter which also starred her previous on screen love interest John Travolta. Nancy Allen’s best known role is Officer Anne Lewis in the RoboCop films. While DePalma went on to The Untouchables with Kevin Costner and Robert DeNiro. Along with Scarface and Carlito’s Way, both starring Al Pacino, and the first Mission: Impossible film with Tom Cruise.
