"The Atomic Brain" aka "Monstrosity"....sounds like a really bad University: "Apply early to Monstrosity University! Get your career started in fields like Atomic Brain Transplants and Caring For The Elderly!"....ahem. -1963.

Taglines: "Chained! To the Devil's love lab!" or "Bodies For Sale!". Both are inaccurate, since only one character is chained and that's the man/dog and the bodies aren't for sale, the old woman just steals them.

Plot: Atomic power has been harnessed and used to transplant brains from one subject to another. How? Well, according to the writers those details were unimportant. Sometimes you needed to be in a giant cylinder and sometimes you didn't. Anyway, an old, occasionally crippled, woman uses her vast wealth to hire three women from overseas as her "servants". She also hires a scientist of questionable moral character to transplant the old bittie's brain into one of the young lady's skulls so she can write the girl into her will and transfer her huge bank account along with her brain. Which one? The hottest one, of course. Which is open to interpretation. The "homely" one gets a cat's brain, as a demonstration to the old woman. Yes, that's right, the cat then has a full-sized human brain crammed into it's tiny, tiny skull. *sigh* Meanwhile, there are two "oopsies" roaming the grounds. A disfigured dog-man and a vaccuous but lovely young woman wrenched fresh from her grave. The girls (finally) figure out something is off kilter when their homely friend climbs onto the roof and begins hissing and growling at them. One of those "Gee, that's peculiar" moments that movies like this are famous for. Things go askew when the morally-challenged scientist gets an idea. SPOILER ALERT! He sticks the old woman's brain into a cat (they're apparently all over the freakin' place) and decides to kidnap the hottie who has been chosen, thereby keeping himself close to the old woman's money. The old woman/cat decides that won't do and causes a cat-ish ruckus that evetually burns the whole place to the ground. Our heroine/hottie, Bea, escapes with her life, her originally equipped brain, and we assume a nice little "inheritance".

Things I learned from this movie: 1- it is not to be confused with the just-as-bad "Creature With The Atom Brain" (1955) which I haven't seen yet, but assume to be awful,

 2- it is also not to be confused with the punk rock band "Creature With The Atom Brain" whom I have also never seen or heard but assume to be awful,

3- apparently all night watchmen have drinking problems, 4- any female in B-movies (including corpses) will be beautiful,

 5- when you put an animal brain in a human their face will change for some reason,

 6- there's a ton of skin in this movie!....well, 60's B-movie skin, you don't actually see anything good,

 7- there is a doctor in this called Dr. Frank who experiments with brains....sound familiar?,

8- for a crippled old woman she sure walks around alot,

9- a human brain weighs approximately 3 pounds and yet somehow still fits inside a housecat's skull, 10- Xerxes the cat, who to his credit played both cats, was owned by the actress who played Bea (the hottie who survives).

BONUS FACT: the actor who played Dr. Frank was also in The Wasp Woman. We'll get to that one.
