Continuity mistake: When Edmund first enters the castle of Jadis and he is crossing the courtyard, the statue of Oreius is visible in the background, which should not appear until the end of the movie. (00:50:15)
Suggested correction: That wasn't Oreius. That was a different Centaur. When Jadis turns foes into stone during the final battle, they don't teleport to her castle, as confirmed later when we see multiple statues in the battle field. The cut to the stone centaur in the castle courtyard is simply a transition (albeit a very misleading one).
