is the phoenix [motif], the bird, which is a symbol of love in a way because there is rebirth, love never dies, it is born again." Visual effects After working on every film since Prisoner of Azkaban, Double Negative was asked to provide visual effects for the final instalments of the story, in Harry Potter and the Deathly Hallows – Parts 1 and 2. Working closely with the film's VFX Supervisor, Tim Burke, the team was led by VFX Supervisor, David Vickery and VFX Producer Charlotte Loughlane. The main team also included 3D Supervisor, Rick Leary and 2D Supervisor, Sean Stranks. Double Negative's work for Part 1 included the corroding Warner Brothers logo and extensive environment extensions of the Burrows and its surrounds. Additional environment work was completed on Xenophilius Lovegood's home, extending it in 3D and culminating in the Death Eaters' attack. Double Negative also advanced the Death Eaters' smoke effects, with the introduction of the 'flayed man' stage in between their smokey, fluid, flying state and their live-action presence upon landing. Other work included the Patronus charm that interrupts the wedding party to inform the guests that Voldemort has taken over the Ministry of Magic. The visual-effects company Framestore produced most of the creature CGI, as in previous films, as well as the animated Tale of the Three Brothers sequence, which was directed and designed by Ben Hibon. Music Composer Nicholas Hooper, who scored Order of the Phoenix and Half-Blood Prince, did not return for Deathly Hallows. Instead, Alexandre Desplat was hired to compose the score for Harry Potter and the Deathly Hallows – Part 1. The film also featured the song "O Children" by Nick Cave and the Bad Seeds.
