James Whale's classic version of Mary Shelley's ghost story made a star of Boris Karloff as the tragic monster. Scientist Henry Frankenstein (Colin Clive) has become alienated from his friends and bride-to-be through his obsessive determination to create life. Frankenstein has created a monster out of body parts acquired by his dwarfish assistant, Fritz (Dwight Frye), and succeeds in giving it life during an electrical storm. However, due to a mistake by Fritz, the creature possesses the brain of a killer, and after the dwarf torments it to breaking point Frankenstein's creation escapes and goes on the rampage, terrorising the local community. Followed by 'The Bride of Frankenstein'.
