<P> Visual Effects Supervisor Tim Burke said that "It was such a major job to stage the Battle of Hogwarts, and we had to do it in different stages of production . We had shots with complex linking camera moves from wide overviews, to flying into windows and interior spaces . So, we took the plunge at the end of 2008, and started rebuilding the school digitally with Double Negative ." He went on to say that "It's taken two years--getting renders out, texturing every facet of the building, constructing interiors to see through windows, building a destruction version of the school . We can design shots with the knowledge that we have this brilliant digital miniature that we can do anything with . With a practical Hogwarts, we would have shot it last summer and been so tied down . Instead, as David Yates finds the flow and structure, we are able to handle new concepts and ideas ." </P> <P> On the quality of 3 - D in film, Burke told Los Angeles Times, "I think it's good, actually . I think people are going to be really pleased . I know everyone's a little nervous and sceptical of 3 - D these days, but the work has been done very, very well . We've done over 200 shots in 3 - D and in the visual effects as well, because so much of it is CG, so the results are very, very good . I think everyone's going to be really impressed with it, actually ." Producer David Heyman spoke to SFX magazine about the 3 - D conversion, saying that "The way David Yates is approaching 3 - D is he's trying to approach it from a character and story point of view . Trying to use the sense of isolation, of separation that sometimes 3 - D gives you, to heighten that at appropriate moments . So we're approaching it in a storytelling way ." </P> <P> In 2012, the visual effects in the film were nominated for an Oscar . The film also won the BAFTA Award for Best Special Visual Effects at the 65th BAFTA Awards in 2012 . </P> <P> It was confirmed that the composer for Part 1, Alexandre Desplat, was set to return for Part 2 . In an interview with Film Music Magazine, Desplat stated that scoring Part 2 is "a great challenge" and that he has "a lot of expectations to fulfill and a great deal of work" ahead of him . In a separate interview, Desplat also made note that John Williams' themes will be present in the film "much more than in part one ." The soundtrack for the film was nominated for Best Score Soundtrack for Visual Media at the 54th Annual Grammy Awards . </P>
