It's official: After finalizing a sale to Roadside Attractions and Lionsgate, Twinless is heading to theaters on September 5. The film originally premiered at the Sundance Film Festival and won the Audience Award: U.S. Dramatic with star Dylan O’Brien, who also serves as an executive producer, winning the US Dramatic Special Jury Award for Acting.

James Sweeney co-stars in, wrote, directed, and produced Twinless, which follows two young men who meet in a twin bereavement support group and form an unlikely bromance.

"I’m delighted to pair up with Roadside and Lionsgate to bring our film into theaters nationwide," he said. "I’m holding ample space for Twinless and look forward to overthinking future press quotes."

Additionally, Miky Lee, Ali Jazayeri, David Gendron, and Liz Destro are executive producers, and Alex Astrachan at Permut Presentations is a co-producer.

The rest of the cast includes Aisling Franciosi, Lauren Graham, Tasha Smith, Chris Perfetti, François Arnaud, Susan Park, and Cree Cicchino.

Roadside Attractions' Eric d’Arbeloff and Howard Cohen described the film as a "genuine comedic crowd pleaser and sophisticated examination of male friendship in the internet age."

The co-presidents continued to share, "Dylan O’Brien’s performance in a dual role is nothing less than a star-defining turn and multi-hyphenate Sweeney declares himself a generational talent both in front of and behind the camera. We are confident the film will connect with theatrical audiences nationwide as strongly as it did at Sundance."

Producer David Permut expressed, "The sharp comedy depicts complex characters in such an irreverent, emotional and hysterical way. The chemistry between Dylan and James is absolutely combustible and it’s a film that is best seen in a theater. I know we have found the right home at Roadside Attractions."

O’Brien will next be seen in Ponyboi, which will be released on June 27.
