Harry Potter

"Magic and stuff, that's a surprise. It's all a bit Harry Potter."

- Martha Jones

Published in the late 20th and early 21st centuries, Harry Potter was a series of novels by British author J.K. Rowling which were extremely popular and spawned a series of film adaptations. The novels chronicled the early life of a young wizard as he was groomed to defeat an evil wizard.

Mentions
The Doctor had read the Harry Potter novels, and cried upon reading the ending of the seventh book. Martha Jones also knew the books and suggested Potter's magic word "expelliarmus" to William Shakespeare to help defeat the Carrionites. The suggestion worked. (DW: The Shakespeare Code) Donna Noble jokingly referred to a centaur she met as Firenze - the name of one of the centaurs in the Potter universe (BBC Audio: Pest Control). A copy of Harry Potter and the Philosopher's Stone (the first Potter novel) can be seen in a display case on Platform One. (DW: The End of the World)

Although originally consisting of seven books, there is a possibly apocryphal account suggesting that at some point several more novels in the series were written, as the Doctor had a complete set of 11 Harry Potter novels in his TARDIS. (EDA: The Gallifrey Chronicles)

Trivia

 * In 2005, Russell T Davies asked Harry Potter's creator J.K. Rowling if she would write for Doctor Who. She refused, saying that she was "was amused by the suggestion but simply doesn't have the time." She was writing the sixth Harry Potter novel at the time.
 * In The Christmas Invasion, a Hogwarts-style uniform briefly appears as the Doctor considers what clothes to wear in his new incarnation.
 * The Shakespeare Code, in which the Doctor references reading the seventh book, was broadcast before the book was published, during a period of intense anticipation for its release. The Doctor doesn't mention the book's title, as it had not been revealed by the time the episode began filming.
 * According to his 2008 autobiography A Writer's Tale, Russell T Davies also considered basing the 2008 Christmas special around an appearance by Rowling.
 * Roger Lloyd Pack, who played the creator of the Cybus Cybermen, guest starred in Harry Potter and the Goblet of Fire alongside David Tennant. The two played father and son. Ironically,this film featured tents that where bigger in the inside, much like the TARDIS.
 * Harry Potter star, Daniel Radcliffe, was a name thrown out by Russell T. Davies to play the Eleventh Doctor.
 * Other actors who have appeared in the Harry Potter films who have been considered for the role of the Doctor include John Cleese (who had a cameo in DW: City of Death), Robbie Coltrane, and Richard Griffiths. Bill Nighy, who will appear in the yet-to-be-released final two Harry Potter films, was reportedly a candidate for the role in 2005.
 * In The Gallifrey Chronicles, written in 2005, a character picks up a copy of the last Harry Potter book in the TARDIS, before replacing it next to its "ten other sequels." While this can be seen as an anachronism, possibly the author was unaware Rowling only planned to publish seven books, it should be noted that since the publication of book 7, Harry Potter and the Deathly Hallows, Rowling has not dismissed the possibility of writing more Potter books in the future (perhaps in the Whoniverse she did in fact write additional volumes). It also should be noted that the title Deathly Hallows is not mentioned in The Shakespeare Code, as the Doctor simply refers to it as "the seventh book". There is precedent for book series to be continued by other authors, i.e. Eoin Colfer's continuation of Douglas Adams' The Hitchhiker's Guide to the Galaxy published in 2009.
 * Zoë Wanamaker, who appeared in DW: The End of the World and DW: New Earth as Cassandra O'Brien.Δ17, also appeared in the film adaptation of Harry Potter and the Philosopher's Stone; a copy of this book is visible in a display case seen in End of the World.

Stephen Fry (narrator for the UK Harry Potter audio books), voiced a character for the Webcast story WC: Death Comes to Time, and was at one point to have written an episode for the revived series, but due to various factors including a change in the Doctor's companion, the episode was never produced.
