In
 Victorian London's Whitechapel section, our story is told in flashback,
 as Dr. Henry Jekyll (Ralph Bates) commits his recent experiences to 
paper, by way of explanation and confession before the police come sot 
take him away. The brilliant doctor seeks an "elixir of life" that will 
grant greatly extended longevity, if not outright immortality, but he 
needs fresh female reproductive organs for his experiments. To achieve 
this ghastly end, he at first employs the services of Byker (Philip 
Madoc), a shady local morgue worker whose banter with the doctor 
contains more than a hint of inferences of necrophilia, and who knows 
the historically infamous "resurrection experts" Burke (Ivor Dean)  and 
Hare (Tony Calvin), a pair of the scurviest gravedrobbers imaginable. 
They make their questionable living by supplying recently-interred 
corpses to medical schools, and now Dr. Jekyll, and, again, Burke's 
banter with the doctor implies "sepulchral sexy-time." No, Jekyll isn't 
that fucked-up, but he feverishly works 'round the clock in his 
apartment's lab for days on end, arousing the interest of an incredibly 
intrusive neighbor family, a trio of characters like something straight 
out of a sitcom and led by man-hungry Susan (Susan Brodrick), who has 
her sights set of the studly Dr. Jekyll.
While fielding constant 
interruptions and intrusions from Susan, Jekyll somehow manages to make 
progress with his experiments, successfully extending the life of a fly 
to over the human equivalent of 200 in human years. But the experiment 
yielded an unexpected side-effect, specifically that it caused the fly 
to transform from male to female. With that, Jekyll shifts experimental 
gears and instead focuses on creating what is in effect a sex change 
serum, meaning his quest requires ever more reproductive organs from 
deceased women. His timing is bad, however, as there is a shortage of 
freshly-dead girls, so, at their suggestion, Burke and Hare simply 
murder what is needed, and the doctor takes the bits that he requires, 
leaving everything else for sale to eager medical schools, all with no 
questions asked. Anyway, while dodging the advances (annoyances) of 
Susan, Jekyll succeeds in his task, tests the formula on himself, and 
transforms into toothsome , randy, and evil Martine Beswick, who 
immediately begins manually exploring her newly-minted tiddies. (In 
actuality only one tiddy, but I'll take what I can get. 

Sister Hyde (Martine Beswick) checks out her newly-minted bodaciousness.
When
 the neighbors get wind of a woman in the doctor's apartment and mention
 that they are curious about her, Jekyll notes that she is his sister, 
"Mrs. Hyde," a recent widow. 
As the corpses of young women begin 
to pile up, the hunt is soon on for "the Whitechapel Murderer" 
(translation: "Jack the Ripper"), while simultaneously the activities of
 Burke and Hare are uncovered and the pair at met with grim fates at the
 hands of a lynch mob. But more serum is needed to refine the process 
and hopefully make it 
more controllable for the user, so Jekyll, getting personally 
proactive, sets out at night into London's  pea soup fog in search of 
prey.
                                                 Dr. Jekyll takes matters into his own hands. But
 Jekyll still needs fodder for his deviant delvings and the authorities 
have a pretty good description of the killer, so Jekyll gets around that
 by transforming into Hyde and murdering his mentor, the lust-driven 
Professor Robertson (Gerald Sim), who suspected Jekyll as being the 
killer, but was thrown off the trail by witnessing a woman leaving 
Jekyll's abode while observing the residence during a police stakeout, 
after which he tells Jekyll of his knowledge of her existence, thus 
ensuring the horny old sod's demise in Hyde's homicidal arms. Then, as 
Hyde, Jekyll hits the nighttime cobblestones in search of a victim. 
                                             Mrs. Hyde (Martine Beswick) stalks the night.  But
 the maniac's identity has been figured out by a blind hurdy-gurdy 
player who has observed events on the streets with his keen ears 
throughout the narrative. He is coerced into giving up Jekyll to the 
police, and in no time Jekyll's home is invaded by cops. Jeky'll 
escapes, but by this time his control over the transformation is random 
at best, with Hyde struggling for dominance, but during a perilous 
escape attempt that finds Jekyll hanging for dear life from a building's
 sill, he changes into Hyde in front of dozens of witnesses (including 
Jekyll's nosy neighbors), but, deprived of her masculine half's 
strength, Hyde loses her grip and perishes upon impact with the street, 
the corpse being a disturbing fusion of both male and female aspects. 
And so ends the bloody trail of the Whitechapel Murderer.
Simultaneously, so ends this dull, plodding slog of a film.
I
 first saw DR. JEKYLL AND SISTER HYDE in edited form at some point in 
the late 1970's and thought it pretty good at the time. But that was as 
perceived v=by 11-year-old eyes, so I had no idea that a lot of the 
film's fat had been excised for commercials. Seeing it uncut at age 57 
was a chore, and I could not wait for it to end. I was something like 
fifteen minutes in when I said aloud "Boy, this movie is BORING!"
Basically
 the J&H story and kind of a proto-slasher, as it blends Jack the 
Ripper and Burke and Hare into the mix, this late Hammer entry came 
during a period when the company's signature red paint blood and risque 
heaving bosoms were being rendered obsolete thanks to more explicit fare
 from other international studios, so my guess is it was made as a bid 
to up their sex & violence ante by way of the then-shocking sexual 
reassigment angle, only using it as hoped-for titillation, but in 
actuality very little of any interest is done with it. In that 
department the film fails utterly, as, despite the presence of her royal
 fineness Martine Beswick veteran of two classic James Bond films (FROM 
RUSSIA WITH LOVE and THUNDERBALL, to be precise), there is fuck all 
that's sexy going on here. 
The characters, nearly the entire lot
 of them, are pretty much ciphers about whom it is impossible to care 
and who just play their roles while offering nothing else, with the 
notable exception of Gerald Sim's super-horny Professor Robertson. The 
guy is very clearly shown to be a poon-hound of the highest calibre, and
 he's a delight whenever she's on screen. At least the film wields 
considerable visual atmosphere, with a Victorian London of cobblestones,
 unsavory street people, dark shadows cast by gaslight, bawdy whores, an
 apparently mad homeless woman who sings to herself throughout the 
narrative, and pea soup fog, along with the sumptuousness of Jekyll's 
fancy tenement digs that come complete a full science lab whose 
aesthetics are at odds with every other set in the movie.
But 
perhaps the biggest disappointment of the film is that it was written by
 Brian Clemens, the co-creator/producer/writer of THE AVENGERS — the 
classic British spy TV series of the 1960's, not the Marvel superheroes —
 a man who often wrote with great cleverness, frequently with a touch of
 the surreal and bizarre. Even his weakest AVENGERS script blew this 
turgid turd straight out of the water. Thankfully, Clemens would redeem 
himself during his time at Hammer by writing, directing, and 
co-producing CAPTAIN KRONOS — VAMPIRE HUNTER, which was shot in 1972 but
 released in 1974. It bore all of the earmarks of Clemens at his best 
and weirdest, but more on that one some other time (possibly next year).
With
 all of that said, I am sad to note that DR. JEKYLL AND SISTER HYDE is 
without doubt the weakest Hammer film that I have seen so far, and I am 
most of the way through their entire roster. We shall see if anything 
from Hammer can rank lower in my estimation of their individual efforts.
 At least the censored version for TV was shorter and moved more 
briskly, thus, perhaps inadvertently, preventing the TV version from 
committing the cardinal sin of cinema by boring the viewer.
This film should have been released in today's climate of gender politics. There would be riots in the streets.
