Arcade Fire's film score features in the new "Her" trailer - watch the video below.
As NME notes, the soundtrack will feature instrumental versions of "Porno" and "Supersymmetry." Both tracks appeared on the Canadian band's UK Number One album, "Reflektor." The latter was apparently written for the film, according to its director Spike Jonze.
In an interview with Hitfix, Jonze explained: "The [band] was working on ["Reflektor"] as they were working on this. Win and I started talking about the score about two years ago, and then it kinda seemed like the record sort of informed the soundtrack and the soundtrack informed the record a little bit, and there's like a song on ["Reflektor"] - the last one, 'Supersymmetry' - that he wrote for the movie, but then it sort of became something else. It's actually the last song in the end credits."
The film, which stars Joaquin Phoenix in the lead role, tells the story of a man who falls in love with a computer operating system (voiced by Scarlett Johansson) following a difficult break-up with his ex-wife, as played by Rooney Mara. Amy Adams, Olivia Wilde and Chris Pratt will also all feature in the film, which is released in UK cinemas on January 24, 2014.
It was revealed last this year that Yeah Yeah Yeahs singer Karen O had also contributed a solo track titled "The Moon Song" for the film's score.
