This adaptation doesn’t quite reach the heights of the 1935 original, yet Kenneth More delivers an acceptable performance as John Buchan’s "Hannay." After an evening out, he encounters a woman (Betty Henderson) and brings her back to his apartment. Upon returning from the kitchen with the offer of tea, he discovers she has other intentions, quickly becoming involved in a murder and espionage plot that threatens national security. Relying solely on a clue referencing a Scottish village and a man lacking a finger, he begins investigating. The use of color photography proves detrimental to films of this type; the atmosphere of danger and suspense is often lessened by overly bright visuals. More puts forth effort, but lacks the necessary presence—or humor—to truly embody the role, and Taina Elg’s appearance as "Fisher" when he travels to Scotland doesn't significantly enhance the story’s final moments. While watchable and featuring a respectable supporting cast—including Brenda de Banzie, Reginald Beckwith, and James Hayter, who each contribute something—the film ultimately feels more like a breezy adventure than a genuine thriller.
