Continuity mistake: When Norma and Helen are in the salon, and they are talking about Carrie going to the prom with Tommy, Norma is getting a fancy hairdo done for the prom. But in the next gym scene, she has her plain braids and a cap on. (00:48:20)
Suggested correction: When you watch the movie leading up to that event, it's obvious that Norma is a tomboy, and is always wearing a ball cap and wearing her hair like that. It's who she is and perhaps decided after her hair was done that it didn't feel right and decided to go back to her look.

Continuity mistake: Near the end of the film, between the time Carrie finishes her bath after the prom and the time her mother stabs her, the wetness of Carrie's hair changes from shot to shot.

Continuity mistake: When the blood is poured over Carrie at the prom, it only covers her left side - hair, shoulder, arm, body. But in the next shot the blood is all over her, especially her hair. The blood on her face is strategically placed, so it isn't in her eyes or cover her too much.
