In 1998, 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 the principal cast be kept strictly British, nonetheless allowing for the inclusion of Irish actors such as the late Richard Harris as Dumbledore, and for casting of French and Eastern European actors in "Harry Potter and the Goblet of Fire" where characters from the book are specified as such. After many directors including Steven Spielberg, Terry Gilliam, Jonathan Demme, and Alan Parker were considered, Chris Columbus was appointed on 28 March 2000 as the director for "Harry Potter and the Philosopher's Stone" (titled ""Harry Potter and the Sorcerer's Stone"" in the United States), with Warner Bros. citing his work on other family films such as "Home Alone" and "Mrs. Doubtfire" and proven experience with directing children as influences for their decision.
