Other mistake: When Michelle Pfieffer hands out menus for the restaurant in the class, they all read them out loud in English. Then when she takes Raul there, he says he can't read it because it's in French.
Continuity mistake: When Angela and her friend are dancing to the music, in the next shot you can see her walking past on the bottom right hand side of the screen, wearing different clothes too. (00:18:58 - 00:19:10)
Continuity mistake: In the scene where it's Michelle Pfeiffer's first day in the classroom, the student who calls her "White Bread" when she walks in goes from one shot where she's sitting in a chair wearing headphones to three quick shots later where she's suddenly standing up dancing without headphones, and then in the next split-second shot she's sitting down again and the girl next to her is wearing the headphones, and then the headphones are back on her head when Pfeiffer walks up to her and asks about Miss Shepard. (00:08:14 - 00:08:55)
Suggested correction: I agree that the female student was standing and swaying next to her seat and a quick shift of the camera showed her seated (relaxed and calm). [8:33 and 8:36] However, the parts about the headphones are not clear or totally accurate. The student next to her had her own set of headphones the entire time. At 9:58, the student in question had her headphones around the back of head - where they were visible because she leaned forward; they could have been there other times as well.
Other mistake: Michelle Pfeiffer's character loses her accent every so often during the movie.
