Withholding the Monster: Reddit Speculation, Viral Paratexts, and Anticipatory Horror around Longlegs

Abstract

This study examines how the promotional campaign for Longlegs transformed absence, secrecy, and fragmented clues into a participatory form of horror before the film reached theaters, and how Reddit users renegotiated that campaign after release. A focused archival netnography analyzed eight public Reddit discussions posted between May and November 2024, covering the official trailer, the in-universe Birthday Murders website, collaborative cipher decoding, early audience reactions, official spoiler discussions, and later assessments of the campaign. At the 5 July 2026 capture, the threads displayed 10,625 comments. A purposive maximum-variation sample of 40 human-authored contributions was examined through reflexive thematic analysis; usernames were excluded and illustrative examples were paraphrased. Five findings emerged. First, visual withholding did not merely preserve surprise; it delegated imaginative labor to audiences, who constructed a monster more frightening than any stable image. Second, ciphers, hidden files, hotline references, and retro-web design turned promotion into a playable archive sustained through collective intelligence. Third, Nicolas Cage's concealed face became an affective promissory object whose anticipated reveal organized fear, curiosity, and theatrical intention. Fourth, release generated an expectation debt: many users praised atmosphere, sound, and framing while judging plot exposition and the visible character against an intensified object imagined through months of promotion. Fifth, the campaign acquired an afterlife partly independent of the film, becoming a benchmark for contemporary horror marketing even among disappointed viewers. The article proposes platformed suspense as a recursive process connecting industrial withholding, collaborative decoding, anticipatory affect, embodied viewing, evaluative recalibration, and retrospective canonization. It demonstrates that social media promotion can function as an experiential extension of cinema rather than a peripheral advertising layer.
