BBC Two is marking 20 years since the release of Harry Potter and the Philosopher’s Stone with  one-off documentary.

The 60-minute programme will uncover the real life traditions of magic at the heart of Harry Potter.

The film goes behind the scenes with the British Library as they search to tell that story through objects in their collection, in an ambitious new exhibition: Harry Potter: A History Of Magic.

JK Rowling, who is lending unseen manuscripts, drawings and drafts from her private archives (which will sit alongside treasures from the British Library, as well as original drafts and drawings from Jim Kay) will discuss about some of the personal items she has lent to the exhibition and give new insight into her writing, looking at some of the objects from the exhibition that have fired her imagination.

The programme will include readings from famous fans as well as following the process of the exhibition, looking at modern magic’s counterparts (from real life wandmakers to Quidditch enthusiasts).
