SPOILER: While filming the bloody prom sequence, Sissy Spacek's trailer was parked behind the set. After being covered in fake blood, for continuity purposes, Spacek refused to wash the effect off. She elected instead to sleep in her bloody clothes for three days of filming.
SPOILER: Ever the stickler for authenticity, Sissy Spacek insisted that she - not a double - be the one whose hand shoots up out of Carrie's grave during Sue Snell's nightmare sequence
# # SPOILER: In the second-to-last scene (where Amy Irving lays flowers on Carrie's grave) to make it more "eerie", the shot was filmed backwards - then run in reverse in slo-mo - to give it a surreal effect. This is evidenced by a background automobile traversing the perpendicular intersection backwards, which the viewer can clearly observe as driving in reverse.
SPOILER: In the scene where the fire hose kills P.J. Soles's character, the water pressure actually burst her eardrums, knocking her unconscious. Soles is actually unconscious when her head rolls to the side from the force of the fire hose. The director decided to keep the shot in.
Screenwriter Lawrence D. Cohen went on to collaborate with composer Michael Gore and lyricist Dean Pitchford and create "Carrie: The Musical", which debuted with the Royal Shakespeare Company, directed by Terry Hands and choreographed by Debbie Allen in Stratford-upon-Avon, United Kingdom in 1988. Later that same year, the production was transferred to Broadway, where 'Betty Buckley' replaced Barbara Cook as Margaret White. The Broadway run only lasted five performances, and it is considered by many to be the most spectacular flop in Broadway history.
Betty Buckley's movie debut.
The film that Tommy and Sue are watching on TV when Tommy agrees to take Carrie to the prom is Duel at Diablo (1966).
The student at the prom being knocked unconscious by the gym fire hose, was a shot of the actress truly being knocked out by the pressure of the water. It was kept in the final cut for being realistic.
The ring that Amy Irving wears throughout the movie was a gift to her from Stephen King the author of the book the film is based on.
Originally, De Palma had used the split screen effect extensively during the prom scene. Disappointed with the results, he re-edited most of the scenes into full frame shots leaving only the few split screen moments that he felt worked.
Amy Irving was originally rather disappointed that many of her larger scenes were cut. A scene featuring Irving and William Katt in the backseat of his truck was cut, for reasons unknown.
Amy Irving admits that she originally hated the script when she first received it. After seeing the finished film, she thought it was simply 'magic' and loved it.
Amy Irving's feature film debut.
In Carrie's house, the statue of a religious figure shot with arrows represents St. Sebastian. It is not a crucifix and does not represent Jesus Christ.
There was originally a scene where Carrie as a little girl is caught talking to a woman sunbathing in the backyard by her mother. Margaret drags Carrie inside and Carrie makes stones rain on the house which tied with the original ending of her burying the house in a shower of boulders. The scene was dropped because the stones didn't have the right effect.
