Corrected entry: During the dragon task, Harry falls off his broom and hangs from a window of the castle; his broom is lying/hanging on the roof above him. Yet, in the wide shot from above, the broom is nowhere to be seen - at least the metal footrest should have been visible.

Correction: Once Harry falls from the first (top) window, down to the window below where his broom is located, the broom is indeed seen on that roof in the overhead shot looking down, albeit rather small.
