Corrected entry: In the scene where the pixies are let lose in their first Defense Against the Dark Arts class, the pixies make a disaster of the classroom, yet when Professor Lockhart runs out and tells Harry, Ron, and Hermione to take care of the rest, Hermione freezes the whole lot of them with one simple spell. Couldn't she have performed this spell when the professor first released the pixies and saved the class a lot of trouble?
Corrected entry: During the final moments in the Chamber, Harry overcomes Tom Riddle (Voldemort) when putting the Basilisk tooth through the diary. If you watch carefully, you will notice that Harry is keeping his right arm idle, as it has also been posioned by the tooth. He keeps striking the diary and finally closes it for one final attack on the cover. Right before he closes it, you see his left hand still poised in the air with the tooth, but as they cut to the closing of the book right away, they show Harry's left hand closing the book with no sign of the tooth. Now they cut back to Harry's face and his left arm is still up holding the tooth.
Corrected entry: The professors at Hogwarts tell the students that they have extensively checked the entire school and can find no trace of the Chamber of Secrets. The Chamber turns out to be an auditorium-sized room under the school connected to hundreds of yards of underground tunnels. The friendly ghosts that can fly through walls should have been able to find it in a few seconds.
Corrected entry: When McGonnagal is telling the class of the Chamber, she says no such Chamber has been found. Well, how could she say that when Hagrid got expelled from school for opening it fifty years ago and Tom Riddle got a special reward for finding the person who opened it?
Corrected entry: This takes place when Harry is writing in Tom Riddle's diary. Each time Harry writes, Tom's reply waits until Harry's writing has completly soaked into the paper. However, when he asks Tom if he knows anything about the Chamber of Secrets, Harry's entry is still soaking into the paper when Tom begins responding. Tom's reply is too long for him to write in the little time that he had to read Harry's question and write back.
Corrected entry: In the forest, Aragog says he has never seen any of the castle except the box he was kept in, but during the memory Tom Riddle casts a spell, and Aragog falls out of the box and leaves the room, indicating that he has seen other areas of the castle.
Corrected entry: The basilisk is supposed to be moving through the plumbing, but when it petrifies people it's in a room or hallway. How does it get out of the plumbing and into the room? It's too big to fit through a tap, drain or toilet. If it has to knock a hole in the pipes and walls to get out, surely someone would have noticed gaping holes everywhere?
Corrected entry: At the end of the film, Dumbledore says that "all exams have been cancelled". What about pupils taking their final exams in 5th and 7th year?
Corrected entry: In the classroom scene where Professor McGonagall is discussing Chamber Of Secrets, a caged baboon is seen masturbating. (00:48:10)
