A film of the same name, Harry Potter and the Order of the Phoenix, is tentatively scheduled to be released in 2007.

Translations and publishing
The first official foreign translation of the book appeared in Vietnamese on 21 July 2003, when the first of 22 installments was released. The first official European translation appeared in Serbia and Montenegro in Serbian, by official publisher Narodna Knjiga, in early September 2003. Other translations appeared later, e.g. in November 2003 in Dutch and German. The English language version has topped the best seller list in France; while in Germany and The Netherlands an unofficial distributed translation process has been started on the net.

In the Czech Republic a college student translated the book in July/September, long before its intended release date, and one 14-year old schoolboy made it available on his private website. This led to confusion, with many newspapers stating that this unofficial translation was done by group of teenagers and the official Czech publisher (Albatros ) announcing that they would sue the schoolboy. Later they retracted this announcement.

In Britain, the blind then-Home Secretary David Blunkett complained about the delay of the cassette version of the book, as well as its projected price.

The Canadian version of the book is made from recycled paper and saved 29,640 trees in the initial print run of 1 million books.
