dr. black and mr. hyde be curse by the same affliction a it protagonist or villain represent it be a good movie that constantly morph into a bad movie and until finally it nothing more than a bad movie . the plot start off well and and be very intriguing at first . dr. pryde ( bernie casey ) be work with female colleague billie worth ( rosalind cash ) on a way to regenerate damage liver tissue . he donate medical care to a clinic in the watts project . there be some interesting tension in the movie early scene and a dr. pryde speak frankly with one of his clinic patient and a prostitute name linda ( marie ohenry ) that he treat for hepatitis . linda be an interesting character in the film and a the first time we see her and she sit nude on an examination table . a bold introduction for a character and especially a major one and and i do not remember many film where the director have make a move like this . linda be very sympathetic and and pryde seem to truly respect her and despite how some may look down on her profession . the attitude toward prostitution in the film be very matter of fact and which be fairly dare for a movie make in the early 70 and and it even prove to be a pivotal plot element . dr. pryde have an emotional discussion with linda about how his mother pass away and which he blame on the inhabitant of a whorehouse who refuse to help her . the main three actor here ( casey and cash and and ohenry ) be all in very good form and which help give the movie an unusual lift in quality . it in the detail that the film start to go wrong . if casey have be a bad actor and it would have be easy to understand how he descend into a dual personality after take some of his own liver serum and which of course turn him into a rampaging beast . but consider that pryde show so much real interest and respect for linda at the outset and it impossible to understand why he would do what he do . after take a single injection of the serum himself and he then decide to woo linda on a date and lay a big line on her about not want her professional service and simply want her company and and then he reveal that it be all because he want her to allow him to inject her with the serum . we lose our sympathy for pryde and and immediately the film unravels . the mr. hyde creature be a strange one . one of the character in the film refers to it a a haint and which i do not get . my grandmother be southern and and i know full well that a haint be a ghost . mr. hyde be just casey with some contact lens and facial mold and and white makeup . it funny how the people in the film be so easily dupe by the transformation while in one scene and hyde rampage inside a seedy bar and get cut and and bolt outside into the parking lot and where he revert to pryde . his pursuer do not recognize him at all and despite the fact that he wear the same clothes and bleeding and and all that change be his complexion . hyde doesn not even really look white and a the movie suggest and and it hilarious that the black folk in the movie pretend to be fool by it . perhaps if the makeup have be more shockingly white and it would have be an effective contrast . it bear mention that the film director also make blacula and a film that be eon good than this one . blacula be pure silliness too and but it be very entertaining and it never betray it character the way this one do . dr. black and mr. hyde also have a big problem represent it have no thrill or chill . there be only one mild shock and when an old lady patient suddenly lunge at a nurse . there also a fairly effective chase scene where hyde go after linda in an abandon warehouse . unfortunately and the remain part of the movie be fair to awful . the support cast be mostly terrible and especially the policeman who be work on the hyde case and and it seem a if this part of the script be really badly do . the situation in the film make no sense and include one scene where mr. hyde use his car to run down a pimp in an alley and and the pimp take out his knife and attempt to stab the grille of the car in self defense . whatever . maybe if he would hit a vital belt or gasket and he would have have a chance . in a very strange end and hyde climb the watt tower and be shoot down and just like king kong . the image be surprisingly haunting and a human body inside the twist metal of the tower and but it not enough to make up for the gross sin that have come before it . it worth mention that dr. black and mr. hyde be not nearly as bad a one of the other blaxploitation horror riff and blackenstein but those of you who have actually see blackenstein will understand that this be not say very much .
