Wizarding World (franchise)

The Wizarding World is a British multi-media franchise revolving around the fictional world of the Harry Potter series of books by J.K. Rowling.

The series began in 1997 with the publication of the original novel, (Sorcerer's Stone in the United States), the first in a series of seven books, later adapted into a series of eight films, and accompanied by various spin-offs in book, film, video games, and theatre.

The series is set in the titular wizarding world, a secret, magical community in which the youth are sent off to wizarding schools to perfect their magical abilities. The novels that began the franchise revolved about the titular Harry Potter, an orphan who discovers his magical heritage on his eleventh birthday, and sent off to attend the prestigious Hogwarts School of Wotchcraft and Wizardry and, over a seven-year period, must prepare for his eventual final confrontation with the notorious dark wizard, Lord Voldemort. Later works set within the same universe included, but are nowhere near limited to, the film series, starring the character of Newt Scamander.

The Wizarding World's connections to the Doctor Who universe are present primarily through their extensive list of shared cast and crew, as well as the DWU's various references to the world, while also sharing some notable crossovers.

Crossovers
The Wizarding World 's crossovers with the Doctor Who universe primarily originate from the crossover video game LEGO Dimensions, along with promotional material for the game. The Harry Potter Team Pack was first added to the game on 27 September 2016, and included the characters Harry Potter and Lord Voldemort, along with the vehicles Enchanted Car and Hogwarts Express. Later, the Fantastic Beasts and Where to Find Them Story Pack, including the character Newt Scamander, the "object" Niffler, the Toy Pad Build MACUSA (Magical Congress of the United States of America), and 6 Fantastic Beasts levels, along with the Tina Fun Pack, which included Tina Goldstein, along with the "object" Swooping Evil; both Fantastic Beasts packs were released on 18 November 2016. Later, the Hermione Granger Fun Pack, including the character Hermione Granger, along with the "vehicle" Buckbeak, was released on 9 May 2017. This addition to the game allowed players to control the franchise's seven playable characters - Harry Potter, Lord Voldemort, Newt Scamander, Jacob Kowalski (through "character changing" from Newt), Tina Goldstein, Queenie Goldstein (also through "character changing", from Tina), and Hermione Granger - and have them play through the A Dalektable Adventure and Dalek Extermination of Earth levels, and explore the Who-themed adventure world, as well as operate K9 and interact with the Doctor's TARDIS.

In turn, this allowed the player to play as the Doctor or the Cyberman during the 6 Fantastic Beasts and Where to Find Them levels, explore the Harry Potter and Fantastic Beasts adventure worlds, and battle in the Hogwarts Quidditch Arena by Night, Arid Animal Habitats, Arctic Animal Habitats, and Hogwarts Quidditch Arena battle arenas, as well as using the related vehicles - the Enchanted Car, the Hogwarts Express, the Niffler, the Swooping Evil, and Buckbeak - in any world.

In promotional material for the game, Wizarding World was represented in the trailer New Adventures Await!, where multiple characters and elements from the franchise appear, alongside elements from Doctor Who. First, Harry Potter appears, flying through New York City on his broomstick, and using a spell to capture the Ghostbusters character Slimer with his wand. Just after this scene, The LEGO Movie character Wyldstyle drives a motorcycle through Diagon Alley, past Flourish & Blotts and Quality Quidditch Supplies, before crashing into Lord Voldemort and flying past Slug & Jiggers Apothecary with the help of the E.T. the Extra-Terrestrial character E.T.. The duo then fly in front of the Moon, which is shining over Hogwarts Castle. Later in the trailer, Lord Voldemort and Harry Potter are among the characters seen running into battle in an Adventure Time location, the Land of Ooo, along with the Twelfth Doctor. Just after this scene, Newt Scamander is seen catching Teen Titans Go! character Beast Boy in his suitcase, and firing his wand towards the camera.

Wizarding World is also represented in the theatrical film The LEGO Batman Movie, alongside Doctor Who, as both Lord Voldemort and the Daleks make appearances. This representation carries through to The LEGO Batman Movie Story Pack in LEGO Dimensions, which also features both Harry Potter and Doctor Who elements. Broadcast on the same day as the Wizarding World's arrival in LEGO Dimensions, a more metafictional crossover occurred in the 2016 Children in Need segment, Looking for Pudsey, as a tie-in to the first film, also released on the same day. The short involved Eddie Redmayne (played by himself), after having just filmed a scene as Newt Scamander, phoning various BBC stars and characters, asking for the whereabouts of Children in Need mascot, Pudsey the bear. Among the individuals he phones is the Twelfth Doctor inside his TARDIS. Redmayne is in-costume as Newt throughout the skit.

Wizarding World references in the DWU
In the 2005 novel, The Gallifrey Chronicles, the Eighth Doctor was said to have the complete set of Harry Potter novels in his TARDIS, including a first edition copy of Philosopher's Stone. Curiously, the same source claimed that there were ten novels in total, as opposed to the seven novels of the real world.

A physical copy of Philosopher's Stone could be seen in the 2005 TV story, The End of the World, in a display case on Platform One.

The 2007 TV story, The Shakespeare Code, contained nods to both the series and its author, J.K. Rowling. First, Martha Jones calls the existence of magic "all a bit Harry Potter", which leads the Tenth Doctor to remark, "wait till you read book seven. Oh I cried". Later, when Potter's spell "expelliarmus" was given life in order to help William Shakespeare defeat the Carrionites, the Doctor exclaimed, "Good old J.K.!"

The 2008 Short Trips: Transmissions short story, Doctor Who and the Adaptation of Death, alleged that Rowling had a descendant called PQ Rowling, who continued the series with the book, Harry Potter and the Half-Moon Dentist.

The First Doctor expressed a familiarity with the series in the 2013 novel, A Big Hand for the Doctor.
