What started as use of a couple of Nero tracks as sound beds for The Great Gatsby movie evolved into a larger collaboration with its director, Baz Luhrmann, including this song and additional scoring work throughout the film. Nero's Dan Stephens told Billboard magazine: "We heard last summer that two of our tracks from 'Welcome Reality' were being used as temporary sound beds in the film. A little after that, Baz came to our studio in L.A. and we talked about writing original music for those parts of the movie. As fans of both the book and his work, we were pretty excited to get working on it."
"We worked closely with Baz to write two pieces for the movie using some elements and themes from Craig Armstrong's score," he continued. "We also added some of the electronic sounds we'd used to other cues in the film to give some continuity to the overall score. One of the cues we'd written then developed into a full original song ['Into the Past'], with vocals from Alana [Watson]. It's based around one of the central themes of the story, that of memory and Gatsby's drive to reshape past events."
