Harry Potter And The Prisoner Of Azkaban
In Harry Potter and the Prisoner of Azkaban (2004), in an earlier scene where Hermione confronts Malfoy a tiny hand could be briefly seen inside the stone gate. Later, Hermione is time-traveling and hides at the exact location. So the directors dropped that little Easter egg in there for us. It is always fun finding the little hidden details directors leave behind for us.
