If you're interested in extra features or extended versions this isn't the box set for you because this only contains the movies with minimal special features. However, this set is very compact and only takes up the space of about two movies in the plastic case. If you've been shopping around you may have noticed that there are two different sets, one with the castle on the cover and the other that has three different faces of Harry. This set (the castle one) is the compact version with a single, larger case that contains all eight discs. The set that has the three faces of Harry is the larger box set that contains a separate plastic case for each movie and also contains more extras and special features.
