spider (2002)

"One does get used to it after just a few years."
Spider (Ralph Fiennes), an acute schizophrenic, is attempting to reintegrate himself into society, after twenty years in an institution, but his illness starts to overwhelm him as he revisits his parents dysfunctional marriage, and his grip on reality becomes more precarious.
A quiet film; not one to shout its virtues, but one that slowly unravels its story, much as the main character unravels mentally.

dead ringers (1988)

"You've got to try the movie star, she's unbelievable."
The Mantle brothers are twins (Jeremy Irons) who run a fertility clinic together, and use their likeness to fool various of their female conquests. But then an actress (Geneviève Bujold) enters the scene, and threatens to split the brothers apart.
Sexual thriller and body horror, something of a specialty for Cronenberg, and one that he excels at.

scanners (1981)

"All right. We're gonna do this the scanner way. I'm gonna suck your brain dry!"
An underground network of people called 'scanners' threatens the world as we know it. These are people with psychic powers and the ability to control others, who led by Darryl Revok (Michael Ironside) is determined to achieve world domination. Cameron Vale (Stephen Lack) is an undiscovered psychic, who is tasked with finding Revok and bringing down his network, by Doctor Paul Ruth (Patrick McGoohan).
A scientist sends a man with extraordinary psychic powers to hunt others like him.
Cronenberg continues his exploration of body horror, this time concentrating on the brain. More money brings better actors and better special effects. A cult classic.

the brood (1979)

"Thirty seconds after you're born you have a past and sixty seconds after that you begin to lie to yourself about it."
Nola Carveth (Samantha Eggar) is under the care of unconventional psychologist Dr. Hal Raglan (Oliver Reed). When the daughter returns home from a visit with her mother covered in bruises, the father (Art Hindle) attempts to stop his wife from seeing the girl. Meanwhile, Nola's parents start being attacked by weirdly deformed children...Her husband starts to suspect there may be a connection with the psychologist's methods.
Physical manifestations of rage come to the fore in this continuing exploration of medical horror by Cronenberg. This one supposedly driven in part by a contencious divorce the director was going through at the time.

shivers (1975)

AKA They Came from Within.
"...disease is the love of two alien kinds of creatures for each other. That even dying is an act of eroticism."
There is a murder/suicide in an exclusive apartment block. The dead scientist had been experimenting on parasites for use within organ transplants. Then other residents start to act weirdly, giving in to wild abandon. Could it be that the scientist developed a parasite that preys on humans, increasing their sexual desire and violent tendancies? A parasite that is now loose within the block?
Early Cronenberg that established his dwelling on medical horror. A sort of sexualised version of 'Night of the Living Dead', which is a good thing, if you are wondering. All this and Barbara Steele.
