“We are about to unfold the story of Frankenstein, a man of science who sought to create a man after his own image without reckoning upon God. It is one of the strangest tales ever told. It deals with the two great mysteries of creation – life and death. I think it will thrill you. It may shock you. It might even – horrify you. So if any of you feel that you do not care to subject your nerves to such a strain, now’s your chance to – uh, well, we warned you.”
Boris Karloff and Edward van Sloan, in Frankenstein.
