The strange case of Dr Jekyll and Mr. Hide

Strange Case of Dr Jekyll and Mr Hyde is the original title of a novella written by Robert L. Stevenson that was first published in 1886. Only in 1912 James Cruze made the movie.
The work is commonly associated with the rare mental condition often spuriously called split personality , wherein within the same person there are two distinct personalities. In this case, the two personalities in Dr Jekyll are apparently good and evil, with completely opposite levels of morality. The novella's impact is such that it has become a part of the language, with the phrase "Jekyll and Hyde" coming to mean a person who is vastly different in moral character from one situation to the next.
