In 1964 Alfred Hitchcock regarded this picturesque Baltimore seaport neighborhood as grim and down-at-the-heels. This is where Louise Latham’s Bernice, the emotionally constipated, man-hating mother of Tippi Hedren’s lead character, resided. By today’s standards, of course, it’s a prime location — red-brick row houses, great harbor view, sea air, cool cafes.
