A grand, sprawling mansion in the English countryside is transformed into a minefield of harbored resentments and unearthed family secrets in director Ben Wheatley’s latest acidic ensemble comedy. Colin (Neil Maskell, star of Wheatley’s 2011 breakout hit Kill List) has his heart in the right place when he welcomes his immediate and extended family to ring in the New Year together at a remote villa, but as the champagne flows and the guests pile in — including Colin’s estranged brother David (Sam Riley, Pride and Prejudice and Zombies), his terminally ill Uncle Bertie (Charles Dance, Game of Thrones), and David’s shifty girlfriend Hannah (Alexandra Maria Lara, Geostorm) — old wounds tear open, and the celebration devolves into a tug-of-war of shifting power dynamics, unexpected loyalties, and explosive catharsis. Shedding the genre adornments of his recent thrill rides Free Fire and High-Rise, Wheatley trades bullets for razor-sharp one-liners in this fast-paced, deliciously dysfunctional firecracker of a comedy that plays like Robert Altman on a caffeine high.
