There’s some lesbian incest in this exploitation film from the UK.
The sophisticated plot was probably stolen from Tolstoy:
A young man fantasizes about fornicating with several women.
Not long after they made this film, Madeleine and Mary Collinson became Playboy’s first twin Playmates in the October, 1970 issue. By then, they had returned to their natural hair color and wore their hair curly. (They either wore wigs for Playboy or had really wild perms. The Playboy article shows them preparing for the trip in London with straight hair and walking around Chicago with curly hair that looks like a perm, but the actual photoshoot shows them with curly hair piled high on their heads, as shown below. To me that looks like a wig piled on a lot of natural hair.)
They followed that with appearances in two 1971 films:
The Love Machine
Twins of Evil – in which only Madeleine did nudity!
(Although Mary had a brief nip-slip in a different scene.)
They also posed nude for various “lad’s mags”:
Just Madeleine
both
To my knowledge, neither of them acted after 1972. Mary raised a family in Italy. Madeleine raised three children in the UK, and later moved to Malta, where the twins had been born. They have both left us. Madeleine died in 2014 from emphysema complications, and Mary passed away in 2021 from broncho-pneumonia.

You’ve got things the wrong way around.
The twins’ natural hair is brown, and it was Madeleine who appeared naked in ‘Twins of Evil’ (although both of them posed nude for publicity shoots).
I never said their natural hair was not brown. That’s obvious from the pictures accompanying the post. I said “wigs” because: (1) their hair in the photoshoot was curly, although they had straight hair a few days earlier in London, and (2) it is piled so high that it looks really artificial and kind of ridiculous (see below). If a perm, it must have used up Chicago’s entire supply of hair spray. (There are pictures of them walking through Chicago with curls, so that may be natural hair in the photoshoot, but the styles in the candid photos look natural, while the photoshoot looks like a wig piled on top of a lot of natural hair.) I changed the verbiage of the original post to make the point clear.
You’re right. It was the other scene where only Mary showed her breast, per Mr. Skin
Yes, Some Like it Sexy was original to Tolstoy, while The Love Machine is clearly a lift from Theodore Dreiser.
What can you say? Jacqueline Susann, author of The Love Machine, certainly knew how to sell books. I read one of her books once, but can’t remember which one. It may have been Valley of the Dolls because I recently ran into a copy on my bookshelves when I was looking for something else. (It was probably left by my ex, who read all of Susann’s books.)
That read wasn’t memorable, but I could see why so many people considered her books as guilty pleasures. I think Valley of the Dolls is one of the most-read books in history. At the time of the author’s death in 1974, it was in the Guinness Book of World Records as the best-selling novel in publishing history, so as of then she kicked the asses of Tolstoy and Dreiser.
In fact, she curb-stomped Theodore Dreiser:
In the first week of release:
* Jacqueline Susann’s Valley of the Dolls: 4,000,000 copies
* Theodore Dreiser’s An American Tragedy: 50,000 copies
* I couldn’t find the first-week sales for The Love Machine, but it sold 4.5 million copies overall, so the first week was probably at least 500,000 because of the pent-up demand generated by Valley of the Dolls. Suck it, Dreiser!
Count Tolstoy may have passed Susann since 1974, thanks to his ongoing readership, especially in Russia, but to this day, Valley of the Dolls is pretty close to outselling War and Peace. They are both in the 30 million copy range, per Google’s AI. (As of now, W&P may be a bit higher.) Neither of them is near the top slot any more. That seems to belong to either The Fellowship of the Ring or Harry Potter and the Philosopher’s Stone. (I have never read a Harry Potter book.)
I wonder if anyone reads Ms. Susann’s books anymore. Certainly they were considered schlock by critics at the time they were written, albeit they sold millions and a lot of people enjoyed them. That sort of guilty pleasure does not necessarily have staying power though. I have never read her myself, I must admit. I did read all of the Harry Potter books however. My kids were really into them, and I read along. They are not just ‘kid lit’, but are actually quite well written.
First time I’ve seen shaved pussies in vintage pics. Legendary.
According to IMDB the Collinson twins were born in Malta on 22 July 1952.
“Some Like it Sexy” was released in August 1969.
The twins would have only celebrated their seventeenth birthday a month before release making them sixteen when the film was made.
… and 17 when they posed for Playboy, which was presumably about March or April of 1970 , following the mag’s usual lead time between playmate photos and publication. (They were wearing quite heavy leather jackets on their walking tour of Chicago, so it was clearly before summer.)
Oh, that Hef.
They were 18 when the photos were published. It hit the newsstands about September 15, give or take, so they were a little less than 18 years, two months!
Wow, fully shaved was a rarity back then.
Some of us would love for it to become a rarity again.
