This is what we found on Wikipedia regarding the Harry Potter Studio Tour departure from Kings Cross Station:

The Wizarding World (previously known as J. K. Rowling's Wizarding World) is an epic high fantasy adventure media franchise and shared fictional universe centred on the Harry Potter novel series by J. K. Rowling. A series of films have been in production since 2000, and in that time eleven films have been produced—eight are adaptations of the Harry Potter novels and three are part of the Fantastic Beasts series. The films are owned and distributed by Warner Bros. Pictures. The series has collectively grossed over $9.6 billion at the global box office, making it the fourth-highest-grossing film franchise of all time (behind the Marvel Cinematic Universe, Spider-Man and Star Wars).

David Heyman and his company Heyday Films have produced every film in the Wizarding World series. Chris Columbus and Mark Radcliffe served as producers on Harry Potter and the Prisoner of Azkaban, David Barron began producing the films with Harry Potter and the Order of the Phoenix in 2007 and ending with Harry Potter and the Deathly Hallows – Part 2 in 2011, and Rowling produced the final two films in the Harry Potter series. Heyman, Rowling, Steve Kloves and Lionel Wigram have produced all three films in the Fantastic Beasts series. The films are written and directed by several individuals and feature large, often ensemble, casts. Many of the actors, including Daniel Radcliffe, Rupert Grint, Emma Watson, Tom Felton, Michael Gambon, Ralph Fiennes, Alan Rickman, Maggie Smith, Helena Bonham Carter, Gary Oldman, Eddie Redmayne, Katherine Waterston, Alison Sudol, and Dan Fogler star in numerous films. Additionally, Jude Law and Johnny Depp feature in two films each. Soundtrack albums have been released for each of the films. The franchise also includes a stage production (Harry Potter and the Cursed Child), a digital publication, a video game label and The Wizarding World of Harry Potter–themed areas at several Universal Destinations & Experiences amusement parks around the world.

The first film in the Wizarding World was Harry Potter and the Philosopher's Stone (2001), which was followed by seven Harry Potter sequels, beginning with Harry Potter and the Chamber of Secrets in 2002 and ending with Harry Potter and the Deathly Hallows – Part 2 in 2011, nearly ten years after the first film's release. Fantastic Beasts and Where to Find Them (2016) is the first film in the spin-off/prequel Fantastic Beasts series. A sequel, titled Fantastic Beasts: The Crimes of Grindelwald, was released on 16 November 2018. A third film, Fantastic Beasts: The Secrets of Dumbledore was released on 15 April 2022. The first Wizarding World-branded narrative video game, Hogwarts Legacy, was released in early 2023. Warner Bros. is also developing a television series for HBO, with a season adapting each of the seven Harry Potter books.
