Trivia, insights & behind the scenes
This expanded the 'Amateur Night' segment from V/H/S (2012), with Hannah Fierman reprising her role as Lily. Director Gregg Bishop was specifically hired because producers loved his short film The Birds of Anger.
The siren myth gets a grimy grindhouse update—ancient Greek femme fatale meets toxic bachelor party culture. Lily's design deliberately evokes both seduction and deep-sea horror, rejecting pretty-monster conventions.
