Continuity mistake: When the kids first react to Delores scraping her nails on the blackboard, a girl near the front of the class, (later revealed as 'Maria') wearing sunglasses, is in the process of sitting in a chair. When Delores then asks them to put the desks back, she is now sitting on top of a different desk further to the right, is now holding a magazine and no longer wearing sunglasses. The short time elapsed makes it impossible for her to have moved.
Continuity mistake: When the sisters are counting the money after their charity concert, Sister Mary Clarence puts a bunch of singles on top of her legal pad right before she talks to Kathy Najimy. When the shot changes the singles are not on top of the pad anymore, but a little further up on the table.
Continuity mistake: When Whoopi Goldberg is pushing herself along the walkway after she is stuck to the chair, you can see her move out of view on the camera angle. They then have the angle from in front of her, still pushing herself along the walkway. They then go back to the previous angle and she is back where she started from without rolling backwards.
Continuity mistake: When Father Thomas tells the Sisters that Delores is a Las Vegas show girl, Sister Mary Robert puts her hands up to her face, but in the next shot she has her hands down by her side.
Suggested correction: The camera cuts back to Father Thomas before it goes back to Mary Roberts. Plenty of time to lower her hands.
No it doesn't. When he says she's a show girl and it cuts to two Sisters, Mary Roberts has her hands up. The next shot is of all four of them and her hands are down.
Continuity mistake: In the shot of Whoopi Goldberg after the class have put glue on her chair, she is looking through the door, and you can just see the bottom of the word 'ass' from 'music class', as the blind covers it. When she opens the door and walks in, you can see the entire 'music class'.
Continuity mistake: In the final song (Joyful Joyful) the camera pans out for an auditorium shot and Jennifer Love Hewitt (black top, red leggings, middle row stage left) is missing from the group. In the close up shots immediately before and after she is visible. (01:34:05)
