<P> A new character in the film, Grawp, Hagrid's giant half - brother, came to life by a new technology called Soul Capturing, developed by Image Metrics . Instead of building the character from scratch, the movements and facial expressions of actor Tony Maudsley were used to model Grawp's actions . </P> <P> Nicholas Hooper was the composer for the soundtrack of the film, following John Williams, who scored the first three films, and Patrick Doyle, who did the fourth . In the new score, Hooper incorporated variations on "Hedwig's Theme", the series' theme originally written by Williams for the first film and heard in all subsequent ones . In March and April 2007, Hooper and the London Chamber Orchestra recorded nearly two hours of music at Abbey Road Studios in London . The score, like the film and book, is darker than previous instalments in the series . To emphasise this, the two new main themes reflect the sinister new character Dolores Umbridge, and Lord Voldemort's invasion of Harry's mind . A Japanese Taiko drum was used for a deeper sound in the percussion . The soundtrack was released on 10 July 2007, the eve of the film's release . For his work on the film, Hooper was nominated for a World Soundtrack Discovery Award . The trailer prominently features the cues "Divine Crusade" by X-Ray Dog and "DNA Reactor" by Pfeifer Broz . Music . </P> <P> The film also featured the song "Boys Will Be Boys" by The Ordinary Boys . </P> <P> At 766 pages in the British edition and 870 in the American edition, Order of the Phoenix is the longest book in the Harry Potter series . Screenwriter Michael Goldenberg described his task to cut down the novel as searching for "the best equivalent way to tell the story . My job was to stay true to the spirit of the book, rather than to the letter". Goldenberg said that Rowling told him, the producers, and Yates that "she just wanted to see a great movie, and gave (them) permission to take whatever liberties (they) felt (they) needed to take to translate the book into a movie she would love". Cutting down the book to meet the time frame of the film, Goldenberg explained, became "clearer when (he) figured out that the organising principle of the screenplay was to narrate Harry's emotional journey". He and Yates "looked for every opportunity to get everything (they) could in there . And where (they) couldn't, to sort of pay homage to it, to have it somewhere in the background or to feel like it could be taking place off - screen". </P>
