The monster created by Jack Pierce had been copywrighted by Universal Pictures, but Mary Shelley's "Frankenstein or the Modern Promoetheus" was public domain. With a limited budget, Hammer revived Dr. Frankenstein and his Creature, played by Peter Cushing and Christopher Lee, respectfully in "The Curse of Frankenstein."
Both Lee and Cushing are excellent, the new generation of Karloff and Lugosi. "The Curse of Frankenstein" was the first Frankenstein movie filmed in color, featuring blood, gore and Hazel Court's cleavage. Throw in some dark humor, this new "Frankenstein" franchise lasted 15 years, just 3 years short of the Universal Monster saga which ran from 1931 until 1948.
