Set against the backdrop of World War II, this uplifting drama follows Catrin Cole (Gemma Arterton), a young Welsh woman who lands a job as a scriptwriter for the British Ministry of Information. Initially tasked with writing the "slop" — the female dialogue — for propaganda films, Catrin proves her talent and is promoted to collaborate with the dashing but reserved screenwriter Tom Buckley (Sam Claflin). Together, they are charged with creating a morale-boosting film about the Dunkirk evacuation, a project that must feel authentic and inspiring, despite being largely fabricated. As Catrin navigates the sexist and chaotic film industry, she finds her voice and a growing bond with Buckley, all while working alongside a cast of eccentric characters, including the aging actor Ambrose Hilliard (Bill Nighy). Directed by Lone Scherfig, Their Finest is a heartwarming and witty exploration of art, love, and resilience, celebrating the power of storytelling to shape reality and lift spirits during the darkest of times.
