A strong debut from director Michael Pearce, with a gripping performance by newcomer Jessie Buckley. So much more than just another serial-killer movie.

[Pearce] gives us a carefully crafted dramatic setup, an intriguingly curated selection of suspects for the crime and all of it building to a fascinating, finely balanced ambiguity in the movie’s climactic stages.

British thriller Beast takes a fistful of tired old tropes — like a hunt for a serial killer, and the ‘ol Joe Eszterhas-style is-he-or-isn’t-he-a-baddie tease — and manages to fashion something fresh, fierce and quite striking from them.

Jessie Buckley is a force of nature in the lead role of this sinewy psychological thriller.

Upgrading a sleeping-with-the-enemy premise familiar from countless B-thrillers with a faintly mythic aura and cool psychosexual shading, Beast also sustains a fresh, frank feminine perspective through Jessie Buckley’s remarkable lead performance.
