Twinless, directed, written by, and starring James Sweeney, has just unveiled its first trailer. The film hits theaters in the U.S. on September 5, 2025, courtesy of Lionsgate and Roadside Attractions.
What the Trailer Reveals
The trailer offered an emotionally powerful glimpse into the lives of twin brothers Roman and Rocky—both played by Dylan O’Brien. After Rocky’s tragic passing, Roman spirals into grief and joins a support group for individuals who have lost twins, where he meets Dennis (Sweeney), forging a raw, intense bond.
Viewers are introduced to unmistakable themes of grief and identity via scenes featuring Roman’s strained conversations with his mother, played by Lauren Graham, and his awkward but revealing friendship with Dennis. The tone shifts quickly from somber introspection to tense suspicion as secrets emerge, setting the stage for a gripping psychological narrative.
Cast & Crew
- Director & Writer: James Sweeney
- Lead: Dylan O’Brien (dual role as Roman & Rocky)
- Supporting: James Sweeney (Dennis), Lauren Graham (Lisa), Aisling Franciosi (Marcie), Tasha Smith, Chris Perfetti, François Arnaud, Susan Park, Cree Cicchino
The film made its world premiere at the 2025 Sundance Film Festival on January 23, 2025, where it received the Audience Award for U.S. Dramatic Competition. O’Brien garnered a Special Jury Award for his dual performance. Critic response has been stellar, with Rotten Tomatoes showing around a 95–96% “Fresh” rating, and Metacritic scoring at 82/100, reflecting universal acclaim.
Twinless approaches heavier emotionally charged material through the lens of dark comedy. The trailer balances sensitive moments—like Roman declaring, “I feel like being a twin kind of ruined me”—with awkwardly funny lines that reveal underlying pain. As their friendship deepens, hidden truths surface and threaten to upend their emotional bond.
TL;DR
With the new trailer making waves and the September 5, 2025 release date confirmed, Twinless is shaping up to be a standout fall release. For readers interested in emotionally driven cinema, nuanced performances, and taboo-breaking indie storytelling—it’s one to watch.
