The official trailer has dropped for Twinless, an offbeat dark comedy centered on twin loss and the strange connections that form in its wake. Written and directed by James Sweeney (Straight Up), the film arrives in theaters on September 5, 2025, distributed by Roadside Attractions and Lionsgate.
Dylan O’Brien stars as Roman, a reserved man grappling with the death of his identical twin, Rocky. When he joins a support group for twin bereavement, he meets Dennis (played by Sweeney), another recent twin loss survivor. As the two grow closer, their bond blurs the lines between friendship, identity, and unresolved grief.
Though the film leans into humor, the trailer hints at more unsettling undercurrents, with both men harboring secrets that could threaten the fragile connection they’ve formed. The cast includes Lauren Graham, Aisling Franciosi, Chris Perfetti, Tasha Smith, and Wrenn Schmidt.
After earning the Audience Award at Sundance 2025, Twinless garnered attention for both its performances and its willingness to explore complicated emotional territory with sharp, often uncomfortable wit.
