Sundance Hit “Twinless” Releases Official Trailer

Twinless had its world premiere at the 2025 Sundance Film Festival where it was met with immense critical acclaim and picked up the Audience Award as well. Now, Lionsgate and Roadside Attractions have announced Twinless’ September 5 theatrical release date.

The film follows two young men who are twins, but struggling to find their own identities. Roman (Dylan O'Brien) and Dennis (James Sweeney) meet in a twin support group and form an unlikely, quickly inseparable friendship. However, as the new duo begin to fully integrate into the life of their new friend, hidden secrets threaten to come to light that could fundamentally alter the world around them.

James Sweeney produces, writes, directs, and stars in Twinless alongside Dylan O’Brien, Lauren Graham, Aisling Franciosi, Chris Perfetti, and Tasha Smith.
