"Director/writer John Dowdle and co-writer/producer Drew Dowdle brought the film to us in a form very close to what you'll see in the theater," said Beltrami. "We'd talked with them a few years ago about how The Hurt Locker was edited without a temp, and was originally conceived not to have a score. They were influenced by that idea with No Escape, and I think it really helped the film to edit it like that."
"The palette of the score is mainly manipulated Asian percussion and modular Eurorack synths, with some string orchestra," Sanders described. "We played with the percussion sounds to really accent the 'stranger in a strange land' feeling in the film. We also used production recordings of some street musicians that were recorded on set. And I even recorded my daughter Roux doing a horrible, high-pitched scream and then slowed it down to help create a long, sustained 'pad' of wailing that channels the young girls' screams in the film."
