Twinless

It stars Dylan O'Brien and Sweeney, alongside Aisling Franciosi, Lauren Graham, Tasha Smith, Chris Perfetti, François Arnaud, Susan Park and Cree Cicchino.

[11] Commenting on Sweeney's direction, Peter Debruge of Variety wrote, "On just his second film, the gifted young helmer demonstrates a sophisticated sense of framing, pace and exquisitely uncomfortable dramatic tension".
