The Waterworld Redemption. Floods of Fear comes from director Charles Crichton, who also collaborated on the screenplay with Vivienne Knight, based on a novel by John and Ward Hawkins. The film features Howard Keel, Anne Heywood, Cyril Cusack, Harry H. Corbett, John Crawford, and Eddie Byrne. Alan Rawsthorne composed the music, and Christopher Challis handled the cinematography. After the collapse of a barrier they were constructing, two prisoners and one guard are swept away by floodwaters. They find themselves at Dr. Matthews’s flooded farmhouse (played by John Phillips), but he isn't there; his daughter Elizabeth (Heywood) is instead. Soon tensions escalate, particularly because Donovan (Keel), one of the inmates, seems to be wrongly convicted of murder and has a desire for retribution... Known for his directing work at Ealing Studios, Charles Crichton does a commendable job combining a suspenseful action thriller with elements of film noir. Though mostly recognized for comedies—his final film was A Fish Called Wanda—Crichton had previously demonstrated an aptitude for noir with the excellent and often overlooked Hunted (1952), starring Dirk Bogarde. The main difference here is that the setting primarily takes place on or near water, which proves effective in creating a dramatic atmosphere. The scenes depicting the flood are quite impressive; whether it’s the characters struggling to survive in the water or the destruction of homes and other parts of the watery environment, there's a palpable sense of danger. Christopher Challis's striking black-and-white photography (known for Footsteps in the Fog and later Arabesque), along with Alan Rawsthorne's fitting musical score (from Uncle Silas/Pandora and the Flying Dutchman), elevate the technical aspects of this British production. Ultimately, it’s the relationships between the characters that truly make this film worth watching. Keel portrays a brooding man burdened by responsibility, yet he remains believable as someone you can rely on in a crisis. Cusack is genuinely unstable; he'd likely attack you without hesitation and harbors concerning intentions toward Elizabeth. Heywood, as the only woman in the story, delivers a strong, stoic performance, constantly facing difficult situations—being submerged, needing to display courage, and navigating romance—all of which she handles well. Corbett, who later gained fame through the popular TV comedy Steptoe & Son, embodies the necessary authority figure within the narrative. Overall, it’s quite good. 7.5/10
