One of the most popular horror classics of all time and an acclaimed sequel to the original Frankenstein. The legendary Boris Karloff reprises his role as the screen's most understood monster who now longs for a mate of his own. Colin Clive is back as the overly ambitious Dr. Frankenstein, who creates the ill-fade bride (Elsa Lanchester). Directed by the original's James Whale (his last horror film) and featuring a haunting musical score, The Bride of Frankenstein ranks as one of the finest films not only of the genre, but for all time.

Louis D'Ascoyne Mazzini's mother had been disowned by her noble familly when she married an Italian musician. When her family refuses to let her be buried at the family home, Louis hits on an idea. He can become the tenth Duke of Chalfont if only those between him and the Duke would die. He decides to take matters into his own hands. He will also find himself torn between a woman from his current life and the widow of one of the unfortunately deceased D'Ascoynes.
