"Ruby" is a horror film with the emphasis on atmosphere and suspense, but it also contains enough creepy special effects and blood and gore to satisfy the most demanding genre fans. Most of it takes place at night, with all kinds of marvelous influences lurking in the shadows. Directed by cult-film director Curtis Harrington (Night Tide, Queen of Blood, Voyage to the Prehistoric Planet, Games, What's the Matter with Helen? Whoever Slew Auntie Roo? The Killing Kind) and featuring an impressive cast including Piper Laurie, fresh from her starring role in Carrie, 1976, as Ruby, and Stuart Whitman (Those Magnificent Men in Their Flying Machines, 1965). The movie begins in 1935, Ruby Clair, beautiful hostess of a Florida gambling house, watches in horror as her gangster boyfriend is gunned down, his bullet-riddled body sinking slowly into a dark, foggy bayou. That same night Ruby's baby is born.
