About halfway into the movie, in the scene where the kids (Anne and Nicholas) are studying the Bible, they get seperated because they are fighting with each other. Anne is then locked into the piano room while Nicholas stays in the studying room. They show Nick studying from a birds-eye view, and on the end of the table is Anna's book. But then in the next scene she studying with that same book! This is impossible because they are locked in their own rooms and have no way of entering each other's rooms!
