Trivia, insights & behind the scenes
The film emerged from Mexico's 2010s underground horror scene, where low-budget filmmakers explored extreme bodily autonomy themes in response to ongoing drug war violence.
Director Martin Mayo allegedly used actual contact microphones on actors during 'recording sessions,' though the actors later disputed how much was performed versus practical sound design.
