Australia's Office of Film and Literature Classification has given an M rating ("requires a mature perspective") to Harry Potter and the Order of the Phoenix, an advisory rating that could discourage parents from allowing their children to see it. The rating is less restrictive than the board's MA 15+, which requires children under 15 to be accompanied by a parent or guardian. Although Roadshow Films, which is releasing the movie in Australia on July 11, had previously appealed M ratings for earlier Harry Potter movies -- with mixed success -- it said it would not do so for the new film.
