James Sweeney's 'Twinless' Debuts at Sundance Festival

Dylan O'Brien stars in 'Twinless,' directed by James Sweeney, which premiered at the 2025 Sundance Film Festival in Park City. The film, a dark comedy, explores themes of grief and identity as O'Brien plays Roman, a man mourning the loss of his twin brother Rocky, also portrayed by O'Brien. Roman forms a complex friendship with Dennis, played by Sweeney, in a twin bereavement support group. Sweeney, inspired by his fascination with twins and pop culture, wrote the script, which he had been developing for ten years. The film showcases O'Brien's versatility and emotional depth, a departure from his previous studio roles, as noted by Sweeney. The premiere was well-received despite some technical difficulties, marking a significant moment for both Sweeney and O'Brien at the festival.
