In December 2008, Brian Eno signed on to compose the film's score. Fran Walsh, a big fan of his work, suggested him to Jackson. Jackson had called Eno to request use of two of his early tracks to evoke atmosphere for the 1970s scenes in the film. When Eno asked if he could compose the whole score, Jackson was surprised, since he had heard Eno did not like working on films. For the film's ending, Eno uncovered a demo he had done in 1973 and reunited with the vocalist to create a proper version for the film, commenting: "That song from 1973 was finally finished in 2008!"
