“Put a woman in your life and one day… you'll wake up and look in the mirror and see a changed man!”

There was a time when the title of this film elicited groans of agony from horror purists. But 50 years of hindsight has lent a fair amount of kitsch credibility.

The good news is that it doesn’t take itself seriously… at all. Sometimes it's more like a Carry On than a Hammer, especially when the morgue attendant, on spotting Burke the bodysnatcher swinging from a gibbet, deadpans: "Burke by name and a berk by nature". 

Writer Brian Clemens has also decided to chuck in every conceivable Victorian London cliché in the book - as well as Robert Louis Stephenson's source novel there's also Jack The Ripper, Burke and Hare, even a bit of Sherlock Holmes in the pathologist-turned-detective who tries to hunt the killer down. 

And to add to this heady brew, the film makers have taken the script and upped the cheese factor by 10, giving the whole film the look of Oliver, with cheeky street urchins, fog shrouded alleyways, annoying organ music and chesty, gin-swilling tarts. 

But there's darkness there, too - the murders are blood-soaked and horrific (you never find out exactly what Jekyll has been slicing out of his victims, but I don't think you'd want to, let's put it that way), and there are even hints at necrophilia when the morgue asistant says: "I've grown very fond of that one". 

The most disturbing image is kept for the murder of Professor Robinson, who, as he's being brutally stabbed to death, is treated to the image of Ralph Bates in a corset and wig doing the evil deed.

Don't think it sounds much like Carry On? Compare these quotes with similar ones from Carry On Screaming and then shut up:

"He… hasn't been feeling himself lately" (about Doctor Jekyll) 

"It's a queer business, sergeant - very queer" (just before Doctor Jekyll is seen leaving a dress shop and making a pass at his male neighbour)

"I haven't seen him (Dr Jekyll)… since I arrived" (Sister Hyde) 

And, best of all: "Put a woman in your life and one day… you'll wake up and look in the mirror and see a changed man!"

This is a great film, in need of major re-appraisal. Full of in-jokes and knowing winks to the audience, it's everything a low-budget horror should be. I'll leave the last word to Hare, who shortly before he gets chucked into a lime pit by an angry crowd, tells Jekyll: "You've got to do bad to do good, ain't ya?"
