In the twilight of his life, Ralph, a once-celebrated screenwriter portrayed with formidable intensity by the late John Hurt, is a man raging against the dying of the light. Confronted with a terminal illness, his sharp wit has turned into a weapon against his devoted wife, Anna (Sofia Helin), and the well-meaning carer, Cassie (Erin Richards), sent to assist him. Determined to control his own fate and spare his family a painful decline, Ralph makes a clandestine and desperate arrangement with a mysterious man known only as The Visitor, played with chilling gravitas by Charles Dance. This gripping drama, directed by Eric Styles, explores the profound moral complexities of choice and legacy as Ralph’s secret plan forces a reckoning with his estranged son, Michael (Max Brown), unearthing long-buried family wounds. A poignant and thought-provoking story, "That Good Night" masterfully balances its somber themes with moments of dark humor and raw humanity, creating a powerful meditation on love, loss, and the fierce desire to author one’s final chapter.
