Produced in Hollywood by Herbert Wilcox, who had been unable to obtain sound equipment in London, this "haunted house" (actually "haunted houseboat") mystery-thriller was nevertheless Great Britain's first "all-talkie." John Loder, the only Englishman involved besides Wilcox, and Mary Brian find themselves invited on board a mysterious, fog-bound houseboat. Soon, several of their fellow passengers fall victim to a disguised madman, who proves to be none other than their host, the Reverend Eph Kelly (veteran matinee idol James Kirkwood). Written by John Willard, the author of the classic The Cat and the Canary, and featuring innovative dialogue scenes, Black Waters ultimately suffered in comparison with Alfred Hitchcock's Blackmail (1930), the first "all-talkie" filmed entirely in England. ~ Hans J. Wollstein, Rovi
