This special explores the return of Obi-Wan Kenobi and Anakin Skywalker to the screen, as well as Ewan McGregor and Hayden Christensen to their classic roles. Director Deborah Chow leads the cast and crew as they create new heroes and villains that live alongside new incarnations of beloved Star Wars characters, and an epic story that dramatically bridges the saga films.

A thrilling journey through legends, belief and folklore, this 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. J.K. 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) talks about some of the personal items she has lent to the exhibition and gives new insight into her writing, looking at some of the objects from the exhibition that have fired her imagination.
