I was in a room when this playing was on a nearby screen, which made me think about all the Harry Potter Movies I've seen and the books that I tried to read as a kid. It focuses briefly on the history of the books and movies, but is mainly a bunch of the actors and directors talking about interacting on the set of the films. The "everyone who worked on the movies is like a family" mood they tired to create is obviously for cameras and fan service; it's the majority of the content overshadowing history and film making facts that could have made for a half interesting video.
