Twinless: Dylan O'Brien's Best Performance Yet?

Ahead of its release in the United Kingdom, Twinless was screened at an intimate media preview in Soho, London. Tucked away in a cosy cinema room, journalists sat in anticipation ready to pass judgement on James Sweeney’s new release. 

Reaching an impressive score of 97% on Rotten Tomatoes, following its release in the United States in September 2025, Twinless has emerged as one of the most innovative dark comedies in recent independent cinema. The film features two young men played by Dylan O’Brien and (Director) James Sweeney who meet in a twin bereavement support group. It follows their blossoming bromance and search for identity without their better halves; touching on themes of loneliness, identity, and forgiveness. Roman (O’Brien) and Dennis (Sweeney) become almost inseparable, with Sweeney’s directive choices cleverly setting the stage for an abrupt rug-pull revealing a twisted, grief-ridden journey of the unexpected, which has permanent consequences for their friendship. Beginning as a light-hearted comedy, the film ultimately unfolds into a darker narrative of violence, anger, and loss; a turning point initiated  when Marcie – Roman’s starry-eyed and naively optimistic girlfriend – reveals Dennis for who he truly is.

Premiering at the Sundance Film Festival, which acts as a showcase for new work from independent film makers, the film claimed the Audience Award for US dramatic films - alongside Dylan O’Brien winning the US Dramatic Special Jury Award. Further recognition followed with a Best Director win at the Seattle International Film Festival and a Directors to Watch title at Palm Springs International Film Festival.  

Twinless is perfect for fans familiar with O’Brien’s previous work (such as Maze Runner, The First Time, and Not Okay) as he delivers a dual-performance of both Roman, a boy-ish, insecure, and heterosexual male, and his deceased twin, a confident, gay individual. Whilst O’Brien’s versatility proves an impressive performance, it should not overshadow that of James Sweeney, who plays a hilarious, slightly awkward, and sarcastic Dennis, and had the attendees of the screening laughing throughout. Overall, the pair’s amazing chemistry was undeniable on-screen, bringing the story to life from start to beginning. 

As the ending credits rolled, I could clearly see why it had won the hearts of film fanatics. After a rollercoaster of emotions that successfully balanced sharp humour with emotional unease, the film’s abrupt ending left the audience eager to stay in its world a little longer. Following its award-winning run in the United States, UK audiences have reason to be excited for its release in February 2026.  

After being named one of Variety’s ‘Top Directors to Watch’, I can’t help but wonder what Sweeney will do next…
