" The other stars of the film are the impressive special effects...but the unexpected charmer is Hagrid's half-brother, a simple, sad giant ...Although entirely rendered in CGI, the giant outacts several of the supporting cast members with a moment of pure pathos." (The Times Online)

In late 2005, Tim Burke, overall VFX Supervisor for Harry Potter and the Order of the Phoenix, (which opened in the US on 11th July, 2007) approached Double Negative to come on board as the lead VFX vendor for the film. Tim was keen to bring Double Negative on board as early as possible in the visual effects development process so as to get the maximum level of creative integration.

Double Negative's shot list was divided up into four distinct georgraphical areas: Hogwarts, both inside and out; the Forbidden Forest, where Harry and his friends encounter Grawp, Hagrid's teenage half brother; the Hall of Phrophecy, a mysterious and cavernous storage space in the Ministry of Magic and the Veil Room, which lies at the very heart of the Wizarding world.

Over a period of 19 months Double Negative fielded a team of well over 250 artists, developers and technicians to deliver approximately 950 VFX shots for the film, a record for any one vendor in the history of the Harry Potter film series.
