‘Twinless’ Review: Dylan O’Brien Mourns His Dead Twin In James Sweeney’s Heartfelt & Unhinged Comedy — Sundance Film Festival

deadline.com:

In writer, director and actor James Sweeney‘s sophomore feature, he navigates loneliness, anxiety, depression and other common millennial pastimes through an equally comedic and heartfelt arc… complete with a few “WTF” moments.

Twinless stars Dylan O’Brien as Roman, a young man grieving the loss of his late twin brother Rocky. At a twin bereavement support group, he meets Dennis (Sweeney), who’s struggling with his own loss.

Missing their respective other halves, the two form a bromance while healing from their shared trauma, but a bizarre secret threatens their newfound friendship.

O’Brien and Sweeney have a comedic chemistry that cannot be denied, with the former alternating between the emotionally insecure and naive Roman, as well as his muscled, mustachioed, hunky twin Rocky, who evokes too many run-ins with “mean gays” who are just as misunderstood as the next.
