Are there any bloopers on the "Prisoner Of Azkaban" dvd?

My uncle said that their was some bloopers of when Hermoine Punched Draco in the face and I guess when they were filming that scene,she accidently did punch him in the face for real and he got mad. That's what my uncle said and I've been trying to find that part and I can't find it,not unless he lied to me or something. Is that part really on the dvd,like on the special features?
