Salisbury had opined that in a film with minimal dialogues, bringing the right nuance was the most challenging, as the big music scenes were not difficult. He added "There are three or four scenes in the film where the music really steps out to the front, which you might think were the hardest to write music for because the music is all on its own and plays such an important role, but, actually, all of those scenes were done in like two days’ writing. The hard things are getting the tiny moments right so you don't lead people down the wrong path."
