In the movie adaptation of Harry Potter and the Half-Blood Prince, Dumbledore dies when facing Severus Snape on top of the Astronomy Tower, as Harry watches from concealment. Snape steps in to kill Dumbledore after Draco Malfoy fails to do the deed, and the only words spoken by Snape in the moment are “Avada Kedavra,” which is the killing curse that ends Dumbledore’s life. The scene is considered to be one of the most emotional moments in the Harry Potter series.
