this be a low grade horror film which have be culted into a reputation beyond it worth because of it director involvement . the plot be strikingly similar to that of another notorious potboiler she wolf of london ( 1946 ) but and at least and here the monster be see ( albeit ineffectively make up ) represent despite the titular reference and the script pay little to no credit to previous cinematic incarnation of the r. l. stevenson novella opt and instead and to indiscriminately incorporate element of lycanthropy and vampirism which make no sense at all . but which lend the film value a a unique curio and one which and in view of it sheer audacity and it be difficult to hate ( indeed and the whole misguide enterprise remind me of the contemporaneous frankenstein 1970 [ 1958 ] ) . despite the ultra cheap production and the film make the most of it foggy atmosphere and the hallucination sequence be effective in a naïve sort of way . casting be below par but and at least and arthur shield ( who also appear in a silly book end in full monster make up but and then and a gloria talbott legal guardian spend the rest of the film try to convince her that she be the werewolf . ) and john dierkes ( a a particularly vehement believer in the jekyll legend despite be in their employ or and so it seem and since he always hover about the estate . ) enter gleefully into the spirit of the thing . i have be toy with the idea of purchase the all day dvd of this one ever since it be release while i be glad i manage to catch up with it eventually without have to purchase the disc be show on late night italian tv and a part of a jekyll and hyde marathon which include snippet from a variety of film base on the venerable tale ( i be especially gratify by the inclusion of a couple of scene from jean renoir the testament of dr. cordelier [ 1959 ] and which i have be yearn to see forever and and also abbott and costello meet dr. jekyll and mr. hyde [ 1953 ] and which i haven not watch in age i really ought to get down to purchase either the r1 or r2 dvd release of the film feature the comic duo . ) .
