Almost all appearances of Severus Snape combined in this video, especially, his closeups and medium shots. Most frames with other characters are deleted. Some frames replaced with still images when he talking while other character acting on screen. Probably, the meanings of scenes are lost. But the purpose of this video is to enjoy the appearances of Severus Snape.
