The novel of "Frankenstein" portrays the creature as a sympathetic, tragic figure who desires only the affection of his creator, Dr. Victor Frankenstein, while the film version, which stars Boris Karloff as the creature, suggests that the creature is monstrous, violent and evil. The 1931 film "Frankenstein" is the most famous adaptation of Mary Shelley's book.
The moment at which the creature comes to life differs between the film and novel version. In Shelley's novel, Dr. Frankenstein alone is witness to the reanimation, and he is so overcome with revulsion that he flees his lab without confronting his creation. Igor, Dr. Frankenstein's assistant, does not appear in the novel, although the "It's alive" scene in the movie remains the most well-known scene from the 1931 film nonetheless. The movie shows Dr. Frankenstein speaking with and accepting of his creation. The creature panics when the doctor's assistant enters the room with a lit torch, and the two men mistake the creature's fear for aggression. They lock it in a dungeon, taunting and torturing it until the creature goes mad and becomes murderous.
Several film adaptations exist from 1910 to the present, many of which give the creature's name as Frankenstein and assign a different name for the role of Dr. Victor Frankenstein.
