Dwyer O’Brien (born July 17, 2002) is an American filmmaker based in Los Angeles. Known for psychologically driven horror and analog-inspired storytelling, his work explores identity, paranoia, digital myth, and belief systems through heightened realism and escalating intensity. His films blur fiction and authenticity, pairing lo-fi textures with erratic, boundary-pushing performances and an unapologetic disregard for conventional restraint. O’Brien independently produced and released the 45-minute cult-horror film TOXOPLASMA (2025), directed and produced by O’Brien and Robert Giles. The film was supported by a self-run digital distribution strategy that generated millions of organic views. He later directed REFLECTION.MP4 (2025), a found-footage psychological horror short that advanced to the finalist rounds at Square Peg Social, the festival curated by Ari Aster and Lars Knudsen. O’Brien’s filmmaking has been described as confrontational and controversial, often provoking polarized reactions for its intensity, moral ambiguity, and refusal to soften uncomfortable subject matter. Recurring themes in his work include constructed realities, religious undertones, psychological fracture, and the tension between private belief and public persona. His aesthetic favors practical effects, in-camera realism, VHS-era texture, and performances that feel volatile, invasive, and emotionally unfiltered. In addition to directing and acting in his own projects, O’Brien has worked in development environments supporting producer Roy Lee at Vertigo Entertainment, informing his understanding of packaging, positioning, and long-term career strategy within the industry.
