The story of Frankenstein's monster has long been one of the staples of horror. The book Frankenstein, written by Mary Shelly, wife of poet Percy Shelly is one of the modern horror stories and is also considered one of the earliest science fiction stories. The 1931 movie Frankenstein is very loosely based on Mary Shelly’s book. One of the most striking differences being that of the appearance of the monster. In the book the monster begins as an almost handsome and well-spoken man and only turns ugly as his skin begins to rot away due to poor blood circulation. For most of us however Frankenstein’s monster is best remembered as the large, groaning brute with a flat head and bolt shaped electrodes sticking out of his neck. Frankenstein stars Boris Karloff as the monster and Colin Clive as inventor Henry Frankenstein.
