I don't mean to infringe anyone's copyright and I will immediately remove this video if the copyright holder has any objections.

The original audio is 5.1. You can get it here: is dot gd/mother_src (please do not share this link as my account might be banned because of it).

I highly recommend the movie. It's the finest sci-fi in years.

I've reuploaded the track because the source audio is very quiet. I had to normalize and compress it a little bit 'cause otherwise you could barely hear it.
