it is about celebration of the Harry Potter movie series on the 20th anniversary of the its first part which is: Harry Potter and the Philosopher's Stone, in which majority of cast is being seen and the way in the movie delivered the idea how everyone receive a letter is a extact similar memory to Harry Potter and the Philosopher's Stone, as harry receive letter from Hogwarts by owls, although this documentary contain interviews, discussion, & experience's.

Without any doubt i recommend it to every one of those who ever read Harry potter novels or watch it movies parts, If  you want to experience magical world, than it is the Master key. i recommend it to a watch with family, friends and kids.

First of all without any doubt the fav thing "about this Documentary Film of Harry potter series" is reunion, Its good to see those faces, who are kids when they start this journey, now they all are aged & this reunion is full of celebrations, smiley faces, their thought's, Interviews and about them, this experience is good and i'm glad i have it because of this Documentary Film.

I watched it on my Laptop nd Purchase it from a store as a soft form of blu-Ray HD.
