The film stars Daniel Radcliffe as Harry Potter, with Rupert Grint as Ron Weasley, and Emma Watson as Hermione Granger.  The film is also the last film to feature Richard Harris as Professor Albus Dumbledore, due to his death that same year.

Rowling's "Harry Potter" series of fantasy novels comprises two distinct societies: the Wizarding World and the Muggle world.  The Muggle world is the series' name for the world inhabited by the non-magical majority, with which the Wizarding World exists coextensively, albeit mostly remaining hidden from the non-magical humans.  The plot of the series is set in 1990s Britain, but in a veiled and separate shadow society wherein magic is commonly used and practiced, and those who can use it live in self-enforced seclusion, hiding their abilities from the rest of the world.  The term "Wizarding World" refers to the global wizard community that lives hidden in parallel with the Muggle world; the different terms refer to different communities within the same area rather than separate planets or worlds.  Any new works taking place in this universe are released under the "J. K. Rowling's Wizarding World" brand. Harry Potter and the Philosopher's Stone (released in some countries as Harry Potter and the Sorcerer's Stone) is a 2001 British-American fantasy film directed by Chris Columbus and distributed by Warner Bros.  Pictures.  It is based on the novel of the same name by J. K. Rowling.  The film is the first instalment in the long-running "Harry Potter" film series, and was written by Steve Kloves and produced by David Heyman.  Its story follows Harry Potter's first year at Hogwarts School of Witchcraft and Wizardry as he discovers that he is a famous wizard and begins his education.  The film stars Daniel Radcliffe as Harry Potter, with Rupert Grint as Ron Weasley, and Emma Watson as Hermione Granger. Religious debates over the "Harry Potter" series of books by J. K. Rowling are based on claims that the novels contain occult or Satanic subtexts.  A number of Protestant, Catholic, and Orthodox Christians have argued against the series, as have some Shia and Sunni Muslims.  Supporters of the series have said that the magic in "Harry Potter" bears little resemblance to occultism, being more in the vein of fairy tales such as "Cinderella" and "Snow White", or to the works of C. S. Lewis and J. R. R. Tolkien, both of whom are known for writing fantasy novels with Christian subtexts.  Far from promoting a particular religion, some argue, the "Harry Potter" novels go out of their way to avoid discussing religion at all.  However, the author of the series, J. K. Rowling, describes herself as a practising Christian, and many have noted the Christian references which she includes in the final novel "Harry Potter and the Deathly Hallows". Ronald Bilius "Ron" Weasley is a fictional character in J. K. Rowling's "Harry Potter" series.

He is a member of the Weasley family, a pure blood family, who reside in "The Burrow" outside Ottery St. Catchpole.  Along with Harry and Hermione, he is a member of the Gryffindor house.

Fantastic Beasts and Where to Find Them is a 2001 book written by British author J. K. Rowling (under the pen name of the fictitious author Newt Scamander) about the magical creatures in the "Harry Potter" universe.

It includes several notes inside it supposedly handwritten by Harry, Ron Weasley, and Hermione Granger, detailing their own experiences with some of the beasts described, and including in-jokes relating to the original series.
