Sissy Spacek was offered a cameo in this sequel to Carrie (1976) which she turned down. However, she did give Katt Shea permission to use some of her scenes from Carrie (1976) for flashbacks.
During filming of the climactic party/bloodbath sequence, it took three attempts to shoot Rachel using her telekinetic powers to shatter the glass doors. On the first take, Emily Bergl flinched, and on the second take, she showed her clenched teeth. On the third take, they were able to finish the scene as they wanted it with her showing no facial reaction. Real glass, shattered by the blowers, was used for this scene, and Emily received multiple cuts on her skin (back, arms, legs, and backside) after the shooting of each take. She is deliberately not shown afterward from the back to hide her injuries.
Aside from archive footage from the first film, Amy Irving is the only actress and character to return for the sequel.
The name of the insane asylum in the film is "Arkham", a reference to a town in the works of H.P. Lovecraft. The name of the asylum in Batman comics is a similar tribute.
The film began as an original story, before producers realised how similar it was to Carrie (1976) and so they made it a sequel.
