Robert Louis Stevenson's book was more of detective story than anything else, hence its called "The Strange CASE of Dr Jekyll and Mr Hyde". It is about Dr Lanyon hearing of these unusual and horrific events and trying to piece them together, and in the final few chapters (Jekyll's letters) the story is finally told. As a book, that was very interesting, though as a film this would have been rather dull, and it is much more exciting to see these events unfold on a screen.
The story is very well-known, a scientist splits his personalities and creates an inhuman tyrannical demon that destroys the lives of both of them as well as many others. Only in the book Jekyll invented the drug because he thought that as every man had only one life and two sides, it is impossible to leave a life that satisfies the urges of both of these sides. So he splits them and tries to lead to separate lives, each undisturbed by the other, though of course he fails. Here it is merely out of reckless curiosity, he does something purely because he can without stopping to think if he should.
It also suggests the idea that Dr Jekyll is responsible for Hyde's murders, not Hyde. This is because Hyde isn't a whole person, therefore he can't be judged as a real person or held responsible for his actions. Hyde is the dark side of Jekyll, and nothing about Hyde wasn't already inside the doctor. Jekyll should never have empowered him and let him run loose. I would agree with this.
A brilliant display of fine performances and dialogue, as well as some very interesting imagery, Dan Curtis' adaptation is a delight.
In particular, Jack Palance is extraordinary in both roles. Showing us carelessness and selfishness and in the end fear and desperation in Jekyll as well as impulsiveness, anger and just pure evil in Hyde.
Outstanding! Particularly towards the end.
