"I always regarded 'Baron Frankenstein' as a forerunner to Dr. Christian Barnard, the South African surgeon who was the first man to transplant the human heart, which he did in 1967... I did my first similar experiment with that particular organ (and lots of other bits and bobs as well) in the Hammer Films production of The Curse of Frankenstein in 1957. It was my first appearance as that enterprising individual, the action taking place during the early part of the 19th century. It proved to be an enormous box-office success, and six more of this anti-hero's adventures were made by the same company, over a period of 15 years."
— Peter Cushing, from his autobiography Past Forgetting (1988).
