Continuity mistake: In the extended edition of The Two Towers, during the 'Elvish Rope' scene near the beginning, the mist disappears and reappears between shots. When Frodo falls and lands at the bottom of the ravine, there is lots of thick, white mist swirling around, but when it cuts to a wider shot, it has nearly all disappeared within a second. In the next close-up shot of Frodo, it has reappeared again.

Continuity mistake: When Ginny snatches 'Advanced Potion Making' from Harry in the common room, and says "Who's the Half-Blood Prince? . That's what it says right here: 'This book is the property of the Half-Blood Prince'", she opens it at a random page in the middle of the book. When Harry sees the words 'This book is the property of the Half-Blood Prince', they are written on the first page. Also, the continuity is wrong as she is shown to switch pages between very quick shots.
