Facts about Harry Potter that you didn't know

"Don't step on my cloak"

After Snape kills Dumbledore and is leading the other Death Eaters out of Hogwarts and through the Great Hall, an accident had occurred on set a few minutes into the shooting: before the actors had started filming, Alan Rickman "turned around in this very sinister way and said, 'don't step on my cloak,'" as the director had instructed the other actors that when shooting began, they were to stay close behind Rickman as they followed him without looking at their feet - a difficult task due to the dragging length of Snape's cloak. As shooting began during the second take, Felton, being the closest person to Rickman in the scene, had accidentally dug his heel into the cloak, causing Rickman's neck to rip back. Felton had reported there was an awkward silence afterward, clear that Rickman was not in a good mood after the accident had occurred. Felton continuously apologized to Rickman afterward, in that Rickman did accept and made a joke of the accident later on.
