Dr. Henry Jekyll (Paul Massie) doesn't feel that he is getting along with his wife Kitty Jekyll (Dawn Addams) in which she's interested in another man Paul Allen (Christopher Lee) and so experiments to make himself looking more charming and attractive but with scientific means of revealing the hidden, dark side of man and releases a murderer from within himself.

This was a difficult story to follow along but I will do my best. We spot a place where mute children are playing or how to communicate aggressively which Dr. Jekyll is in charge of and then has a discussion with Dr. Ernst Litauer in ehich he shows his latest experiments a drug in which he uses on a monkey as this shows on how this animal goes crazy. This moment looked a bit disturbing to watch.
Later on in the story there's many pointless conversations with the main characters but however, Dr. Jekyll tries to talk to his wife Kitty as he really wants her and she shows no interest in which their discussions are very mediocre. I just wonder when the horror comes into the story after all of this.
The horror kicks in slowly but surely when Jekyl uses his formula and we see him having a somewhat seizure but it lacked a bit of inspiration in which it needed to pick up the pace to entertain the audience.
Afterwards we spot some pointless ballroom dancing with Kitty and Paul Allen attending the party. A good shot on now Mr. Hyde appearing from his horse and carriage to join along. He is clean cut and a womaniser too with his wicked charm. THis seemed to draw some fair attention. Yet nothing to brag about either.
However, in a situation a woman who has the hots from him dances with him and when he wants to stop dancing with her he is aggressive in which this looked mildly intense which worked in well along with her trying to get someone to beat him up later on. This is when the horror is about to strike. Mr. Hyde whacks him over the head a multiple times in which this made me wonder if he would kill this person. It did make me somewhat cringe.
Later on in the story Mr. Hyde sees a snakecharmer doing a show with her snake which there's good camera takes on her dancing with this serpent as the situations looked truly mysterious. After her performance he introduces himself to her and acts charming towards her which was a half decent effort in the film.
What really grabbed my attention was when a few broads he plans to come home with set him up so someone can knock him out which looked powerful and later on he turns back to Dr. Jekyll. This scene I will admit was well done.
The next day at the same ballroom there's pointless dirty dancing type women doing the can can dance which seemed to be a drawing card to the scene but to me it looked utterly stupid.
While this is going on Hyde gets violent with Kitty plus he uses a snake in which Paul is pitted against this reptile so the horror does kick in but it wasn't all that great and we've seen better horror flicks. Yet with all this happening Kitty seems to be under a spell leading to her suicide which I won't give away. This looked quite powerful.
Then things really unravel when Hyde can't control himself and kills others that are beyond his control which looked strongly done. When he is Jekyl he looks at a reflection in a mirror which reveals Hyde talking coldly towards him as well as controlling him later on. I had to admit this was probably the vest part of the story but not enough to save it from bombing.
Bottom line is I found Hammer Horror films to be slightly amusing even if some were mediocre but this one bites the big one. The story is very slow and hard to follow. It doesn't have enough suspense throughout the plotlines. Better off next time.

The acting is better than the film itself in which Paul Massie (Dr. Henry Jekyll / Mr. Edward Hyde) shows a great versatality with both characters that he portrayed. At first looking scruffy and acting stressed as well as being out of it which looked dated but still showed good characteristics in this role. Then when he changes into another character I wondered if it was portrayed by another cast member but it wasn't at all. Shows off a nice wicked charming and calm attitude as well as convincing when he acts deadly with his evil deeds. Knows how to act stressed when he turns back into his original character.
Dawn Addams (Kitty Jekyll) shined on well with her heatlhy good girl middle aged looks. Does well with her clear speaking whenever she has a discussion. Was also very sharp with her reactions on stuff. She indeed proved herself to be a worthy character actress with all that she did in her performance.
Christopher Lee (Paul Allen) was another one with a sharp personality. He shows off a high powerful type with his interactions and did it with good slick style. Showed off a perfect aggression when needed in a scene in which he coems across as someone you wouldn't want to mess with. He made those moments perfectly believeable. Offers a nice charming attitude too. HE was a ball of energy and great spunk along with great charisma too.

Both David Heneker and Monty Norman composed this piece as at times it's okay and other times didn't tickle my fancy. Alot of drum rumblings as well as some strong violin type classical music whoich sounded fair for the suspenseful moments. However the music used for the ballroom scene's I didn't really care for. But that is just me. Sometimes it was catchy when Jekyl turns to Hyde in which they focused well on this scene.
