“I’m delighted to pair up with Roadside and Lionsgate to bring our film into theaters nationwide. I’m holding ample space for Twinless and look forward to overthinking future press quotes.” said Sweeney on the announcement.
“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,” says Permut.
Roadside Attractions co-presidents Eric d’Arbeloff and Howard Cohen added, “Twinless is both a genuine comedic crowd pleaser and a sophisticated examination of male friendship in the internet age. 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.”
Three Point Capital financed the feature. The deal was negotiated by Charlotte Koh on behalf of Lionsgate and Roadside Attractions. Sejin Croninger negotiated for Republic Pictures.
