The score, composed by Jóhann Jóhannsson, is equally impressive, adding to the sense of unease and tension. The use of eerie sound effects and haunting music creates a sense of foreboding, which is present throughout the film.
Benicio del Toro's performance as Alejandro Herdia is equally impressive, as he brings a sense of depth and nuance to the character. Herdia's backstory, which is slowly revealed throughout the film, adds a layer of complexity to his character, making him more than just a skilled hitman.
The film's cinematography, led by Roger Deakins, is stunning, with a muted color palette that perfectly captures the desolate and gritty atmosphere of the US-Mexico border. The use of close-ups and medium shots adds to the sense of tension and unease, drawing the audience into the world of the film.
