Contagious violence

by Mighty_Emperor | created - 10 Dec 2011 | updated - 2 weeks ago | Public

Often very similar to zombie movies but the dead aren't reanimated, instead some kind of "infection" turns the population into raging cannibals.

Despite not ticking all the boxes for a zombie film there is plenty of crossover (especially as The Last Man on Earth inspired Romero's zombies) and a fan of the undead should be just fine with these too, especially as classifying them separately from zombies means any extra abilities (like running fast, and even free running) won't be too jarring. Most are worth a rental although some, like almost all the I Am Legend adaptations, 28 X Later, The Crazies, Quarantine and Pontypool are good enough to seek out.

See also: The vengeful dead (another group of films often grouped with zombie films) and contagion (for films where a lot of people get sick and just die). There is also they walk amongst us for more subtle takeovers (as some of the films on this list involve infection by an alien virus or parasite in order to violently take over the world - see Slither as a good example)

1. The Crazies (1973)

R | 103 min | Action, Horror, Sci-Fi

63 Metascore

The military attempts to contain a manmade combat virus that causes death and permanent insanity in those infected, as it overtakes a small Pennsylvania town.

Director: George A. Romero | Stars: Lane Carroll, Will MacMillan, Harold Wayne Jones, Lloyd Hollar

Votes: 10,041 | Gross: $0.15M

Here for the thumbnail graphic, the list starts below:

2. The Mad Ghoul (1943)

Not Rated | 65 min | Horror, Sci-Fi, Thriller

A university chemistry professor experiments with an ancient Mayan gas on a medical student, turning the would-be surgeon into a murdering ghoul.

Director: James P. Hogan | Stars: David Bruce, Evelyn Ankers, George Zucco, Robert Armstrong

Votes: 541

Possibly not contagious but definitely induced, zombie-like cannibalism amongst the living, which is exactly what we are looking for here.

3. The Brain Eaters (1958)

TV-PG | 61 min | Sci-Fi, Horror

The inhabitants of a small Illinois town begin disappearing after a strange cone is found sticking out of the ground nearby.

Director: Bruno VeSota | Stars: Ed Nelson, Alan Jay Factor, Cornelius Keefe, Joanna Lee

Votes: 1,047

An early pioneer of the parasitic possession theme.

4. The Last Man on Earth (1964)

Not Rated | 86 min | Drama, Horror, Sci-Fi

When a disease turns all of humanity into the living dead, the last man on earth becomes a reluctant vampire hunter.

Directors: Ubaldo Ragona, Sidney Salkow | Stars: Vincent Price, Franca Bettoia, Emma Danieli, Giacomo Rossi Stuart

Votes: 15,792

The first "I Am Legend" adaptation and an important one for zombie movie fans researching the sub-genre's history because, while the infection and general mythology is more vampiric, a lot of the feel of the film inspired Romero when he was making Night of the Living Dead.

The film is public domain.

5. I Drink Your Blood (1970)

R | 83 min | Horror

A group of hippies wreak havoc on a small town and a young boy, whose grandfather and sister were attacked by them, decides to get even, with deadly results.

Director: David E. Durston | Stars: Bhaskar Roy Chowdhury, Jadin Wong, Rhonda Fultz, George Patterson

Votes: 2,953

The film is public domain.

6. The Omega Man (1971)

PG | 98 min | Action, Drama, Sci-Fi

56 Metascore

Lone survivor, doctor Robert Neville, struggles to create a cure for the plague that wiped out most of the human race while fighting The Family, a savage luddite death cult formed by the zombie-like infected to erase the past.

Director: Boris Sagal | Stars: Charlton Heston, Anthony Zerbe, Rosalind Cash, Paul Koslo

Votes: 26,965 | Gross: $8.72M

Also based on "I Am Legend"

7. Doomwatch (1972)

PG | 92 min | Mystery, Sci-Fi, Thriller

The waters surrounding an island become contaminated by chemical dumping, and people who eat fish caught in those waters become deformed and violent.

Director: Peter Sasdy | Stars: Ian Bannen, Judy Geeson, John Paul, Simon Oates

Votes: 714

8. The Crazies (1973)

R | 103 min | Action, Horror, Sci-Fi

63 Metascore

The military attempts to contain a manmade combat virus that causes death and permanent insanity in those infected, as it overtakes a small Pennsylvania town.

Director: George A. Romero | Stars: Lane Carroll, Will MacMillan, Harold Wayne Jones, Lloyd Hollar

Votes: 10,041 | Gross: $0.15M

This helped define these films early on. Romero wanted to try something different after redefining the zombie movie but he didn't stray far from home, just making the infected faster.

9. Messiah of Evil (1973)

R | 90 min | Horror

A young woman goes searching for her missing artist father. Her journey takes her to a strange Californian seaside town governed by a mysterious undead cult.

Directors: Willard Huyck, Gloria Katz | Stars: Michael Greer, Marianna Hill, Joy Bang, Anitra Ford

Votes: 2,661

A difficult one to classify as the cultists are often called vampires (but they eat meat and go out in daylight, there is an I Am Legends feel to them though) or ghouls, but we do see this spreading to the woman Thom meets and the cop, so I'm putting it here.

10. Shivers (1975)

R | 87 min | Horror, Sci-Fi

The residents of a suburban high-rise apartment building are being infected by a strain of parasites that turn them into mindless, sex-crazed fiends out to infect others by the slightest sexual contact.

Director: David Cronenberg | Stars: Paul Hampton, Joe Silver, Lynn Lowry, Allan Kolman

Votes: 15,854

The parasitic infection doesn't make the hosts become quite as violent as they do in other films (and they aren't cannibals) but they are very "insistent" that other people also become infected to the point it becomes violent, sinister and just plain nasty.

11. Rabid (1977)

R | 91 min | Horror, Sci-Fi

A young woman develops a taste for human blood after undergoing experimental plastic surgery, and her victims turn into rabid, blood-thirsty zombies who proceed to infect others, which turns into a city-wide epidemic.

Director: David Cronenberg | Stars: Marilyn Chambers, Frank Moore, Joe Silver, Howard Ryshpan

Votes: 13,904

12. Blue Sunshine (1977)

R | 94 min | Horror, Thriller

A bizarre series of murders begins in Los Angeles, where people start going bald and then become homicidal maniacs. But could the blame rest on a particularly dangerous form of LSD called Blue Sunshine the murderers took ten years before?

Director: Jeff Lieberman | Stars: Zalman King, Deborah Winters, Mark Goddard, Robert Walden

Votes: 2,299

13. The Grapes of Death (1978)

R | 85 min | Horror

A young woman discovers that the pesticide being sprayed on vineyards is turning people into killer zombies.

Director: Jean Rollin | Stars: Marie-Georges Pascal, Félix Marten, Serge Marquand, Mirella Rancelot

Votes: 1,927

The slow, sadistic, pustule-pocked, psychopaths are clearly not zombies and even have relapses where they show remorse or ask for help. This plus the setting in desolate upland France (presumably somewhere in southern-central France from the landscape) all help to give this a genuinely creepy atmosphere, that sometimes borders on backwoods horror. It is a very different feel to a lot of the post-28 Days Later infected films (which with their usually fast and brutal infected tend to lead to more action-horror movies) but it is definitely worth a watch if you are looking for something a little different, perhaps with the feel of something like The Children (2008).

14. The Children (1980)

R | 93 min | Horror, Sci-Fi

A nuclear-plant leak turns a bus-load of children into murderous atomic zombies with black fingernails.

Director: Max Kalmanowicz | Stars: Martin Shakar, Gil Rogers, Gale Garnett, Shannon Bolin

Votes: 1,619

15. Nightmare City (1980)

R | 88 min | Horror, Sci-Fi, Thriller

An airplane exposed to radiation lands, and blood drinking zombies emerge armed with knives, guns and teeth! They go on a rampage slicing, dicing, and biting their way across the Italian countryside.

Director: Umberto Lenzi | Stars: Hugo Stiglitz, Laura Trotter, Maria Rosaria Omaggio, Francisco Rabal

Votes: 5,069

From Wikipedia: "Director Umberto Lenzi felt the film was not as much as zombie film but a 'radiation sickness movie' with hints of an anti-nuclear and anti-military messages"

Lenzi only did one proper zombie film - Black Demons (often given as Demoni 3, even though it isn't part of the series). Instead this is more a way to combine the zombie and cannibal genres, although not that successfully.

16. Cannibals in the Streets (1980)

R | 96 min | Horror, Sci-Fi, Thriller

Giovanni Lambardo Radice and John Saxon are Vietman vets that bring back contagious virus that turn people into cannibals when bitten.

Director: Antonio Margheriti | Stars: John Saxon, Elizabeth Turner, Giovanni Lombardo Radice, Cinzia De Carolis

Votes: 2,665

aka Cannibal Apocalypse

Another interesting attempt to make a zombie/cannibal film with bites infecting people with violent cannibalism but it rarely makes the best use of its premise, with only a handful of stand-out scenes. Unfortunately, John Saxon didn't realise what he had signed himself up to and refused to get involved in the cannibalism which meant that his character (the core of the film) is presented with the real internal conflict this type of film should have.

17. Toxic Zombies (1980)

R | 89 min | Horror, Sci-Fi

After drug crops are sprayed with a chemical by a passing airplane, the growers of the crop are poisoned by the chemical and turn into zombie-like mutants.

Director: Charles McCrann | Stars: Charles McCrann, Beverly Shapiro, Dennis Helfend, Kevin Hanlon

Votes: 689

18. Night of the Comet (1984)

PG-13 | 95 min | Comedy, Horror, Sci-Fi

A comet wipes out most of life on Earth, leaving two Valley Girls fighting against cannibal zombies and a sinister group of scientists.

Director: Thom Eberhardt | Stars: Catherine Mary Stewart, Kelli Maroney, Robert Beltran, Sharon Farrell

Votes: 16,773 | Gross: $14.42M

So Eighties it hurts.

A comet kills everyone not protected by steel, turning them to dust. Some with only slight exposure are turned into violent, oddly-coloured cannibals, but we only see a few of them - the biggest threat is other survivors.

19. Impulse (1984)

R | 91 min | Horror, Mystery, Sci-Fi

After a small earthquake in a tiny, quiet town, local citizens start to exhibit bizarre, violent and self-destructive behaviour.

Director: Graham Baker | Stars: Tim Matheson, Meg Tilly, Hume Cronyn, John Karlen

Votes: 1,126 | Gross: $2.50M

20. Mutant (1984)

R | 99 min | Horror, Sci-Fi, Thriller

Two brothers discover that the residents of a small Southern town are being infected by a form of toxic waste, turning them into blood-ravenous zombies.

Directors: John 'Bud' Cardos, Mark Rosman | Stars: Wings Hauser, Bo Hopkins, Jody Medford, Lee Montgomery

Votes: 1,610

A classic example of this type of film - it provides the kinds of thrills a zombie movie fan is looking for, without any of the post-Romero rules: no reanimated dead, bites aren't infectious and headshots aren't required, but did it have to be quite so dark? Dark as in the light conditions, not the story. At a lot of crucial moments all you get are abstract dark blobs moving against a black background, something that might have worked in a cinema once the viewers eyes had adjusted to the light, but one home media any effect there might have been is a hindrance to the viewer in working out what is actually going on.

21. The Spirits of Jupiter (1984 Video)

Director: Hal Barwood | Stars: Sam Waterston, Kathleen Quinlan, Yaphet Kotto, Jeffrey DeMunn

Votes: 1,970 | Gross: $1.92M

23. The Stuff (1985)

R | 87 min | Comedy, Horror, Sci-Fi

A delicious, mysterious goo that oozes from the earth is marketed as the newest dessert sensation, but the tasty treat rots more than teeth when zombie-like snackers who only want to consume more of the strange substance at any cost begin infesting the world.

Director: Larry Cohen | Stars: Michael Moriarty, Andrea Marcovicci, Garrett Morris, Paul Sorvino

Votes: 11,792

I'm not 100% sure of this so will need to rewatch it.

24. Demons (1985)

Not Rated | 88 min | Horror

A group of random people are invited to a screening of a mysterious movie, only to find themselves trapped in the theater with ravenous demons.

Director: Lamberto Bava | Stars: Urbano Barberini, Natasha Hovey, Karl Zinny, Fiore Argento

Votes: 18,138

A touch of demonic infection.

25. Creature (1985)

R | 97 min | Horror, Sci-Fi

An expedition to Titan uncovers an alien being, that goes on a rampage.

Director: William Malone | Stars: Stan Ivar, Wendy Schaal, Lyman Ward, Robert Jaffe

Votes: 3,033 | Gross: $4.78M

As well as being a blatant Alien rip-off, there are contagious violence elements. I suspect this was done to keep the rather poor Creature in the background (and shadows) as long as possible, instead relying on the cheaper option of people in make-up, pulling faces.

So a crossover with my Space Horror list.

26. Night of the Creeps (1986)

R | 88 min | Comedy, Horror, Sci-Fi

Alien brain parasites, entering humans through the mouth, turn their host into a killing zombie. Some teenagers start to fight against them.

Director: Fred Dekker | Stars: Jason Lively, Tom Atkins, Steve Marshall, Jill Whitlow

Votes: 18,604 | Gross: $0.59M

Classic 80s flick (for the full retro hit watch this in a double bill with Night of the Comet), with alien parasites on the loose causing all sorts of problems by animating the living and the dead.

27. Demons 2 (1986)

An unofficial sequel to "Mutant".
