In 1999, Rowling sold the film rights of the first four Harry Potter books to Warner Bros. for a reported £1 million ($1,982,900). Rowling demanded that the principal cast be kept strictly British but allowed for the casting of Irish actors such as the late Richard Harris as Dumbledore and of foreign actors as characters of the same nationalities in later books. After extensive casting, filming began in October 2000 at Leavesden Film Studios and in London, with production ending in July 2001. Harry Potter and the Philosopher's Stone was released in London on 14 November 2001. Reviewers' comments were positive, as reflected by an 80% Fresh rating on Rotten Tomatoes and by a score of 64% at Metacritic, representing "generally favourable reviews".

Uses in education and business
Writers on education and business subjects have used the book as an object lesson. Writing about clinical teaching in medical schools, Jennifer Conn contrasted Snape's technical expertise with his intimidating behaviour towards students; on the other hand Quidditch coach Madam Hooch illustrated useful techniques in the teaching of physical skills, including breaking down complex actions into sequences of simple ones and helping students to avoid common errors. Joyce Fields wrote that the books illustrate four of the five main topics in a typical first-year sociology class: "sociological concepts including culture, society, and socialisation; stratification and social inequality; social institutions; and social theory".
Stephen Brown noted that the early Harry Potter books, especially Harry Potter and the Philosopher's Stone, were a runaway success despite inadequate and poorly organised marketing. Brown advised marketing executives to be less preoccupied with rigorous statistical analyses and the "analysis, planning, implementation, and control" model of management. Instead he recommended that they should treat the stories as "a marketing masterclass", full of enticing products and brand names. For example, a real-world analogue of Bertie Bott's Every Flavour Beans was introduced under licence in 2000 by toymaker Hasbro.
