Monster Tumor/Bad Movie

An amazingly bad movie from the VHS era where a woman is exorcised by a televangelist and coughs up a tumor, which crawls out of the trash and possesses her son, driving him to kill and bring bodies home to feed the tumor

Alien (1979)

Rating: ★★★★★
Alien Nasty on a Spaceship

One of the most influential films on this site, producing a host of sequels and making the careers of all involved. At heart, a simple monster on a spaceship film, it is made into a classic through Ridley Scott’s relentless suspense and H.R. Giger’s design work

Aliens vs Titanic (2017)

Aliens vs Titanic (2017) poster
Rating: ★★
Stranded on a Planet with Alien Parasites

Full marks for the title. Rather than any spacegoing version of Titanic, we have a spaceship named Titan1-C, which is soon abandoned and thereafter a cheesily ridiculous film about alien chestbusters

Apollo 18 (2011)

Apollo 18 (2011) poster
Rating: ★★★
NASA Moon Landing/Alien Possession Found Footage Film

Clever and well made Found Footage film about a NASA crew encountering something alien on The Moon’s surface. Falls somewhere between Alien, Apollo 13 and Paranormal Activity

Hostile Alien Planet/Alien Nasty

The rapper turned filmmaker Flying Lotus directs a copy of Alien with an amnesiac crewmember of a ship landed on a hostile planet where the crew are hunted by an alien nasty

Baby Blood (1990)

Baby Blood (1990) poster
Rating: ★★★
Woman Impregnated by a Blood-Drinking Parasite

A wildly deranged and gore-drenched ride. Imagine Rosemary’s Baby with an Alien chesburster where a woman is impregnated by a parasite that maintains a monologue as it urges her to kill and drink blood to feed it.

Bad Milo! (2013)

Rating: ★½
Demon Inhabits a Man's Ass Comedy

A comedy about a demon that appears out of a man’s ass!!! This has the dementia to be a potential midnight cult hit but misses the mark by a wide mile and stumbles around obvious targets in predictable ways

Batman and Superman: Battle of the Super Sons (2022)

Batman and Superman: Battle of the Super Sons (2022) poster
Rating: ★★★
Comic-Book Superheroes/Animation

Animated film featuring a team-up between the sons of Batman and Superman, which ends up being far more fun than you expect

Battle for Pandora (2022)

Battle for Pandora (2022) poster
Rating: ★★
Planetary Exploration/Alien Body Snatchers

The Asylum’s mockbuster take on Avatar: The Way of Water, which ingeniously exploits the fact that Saturn has a moon called Pandora. The rest is a low-budget body snatchers film

Brain Damage (1987)

Brain Damage (1987) poster
Rating: ★★★★
Addictive Brain Parasite

The best film from the great and underrated Frank Henenlotter about the relationship between a man and a parasite in his brain that feeds him drugs to make him go and kill

Brain Dead (2007)

Brain Dead (2007) poster
Rating: ★½
Alien Zombie Splatter

Not to be confused with the Peter Jackson Braindead, although the similarity of titles only emphasizes how weak and unfunny this 1980s splatter homage comedy is in comparison

The Brain Eaters (1958)

The Brain Eaters (1958) poster
Rating: ★★
Alien Body Snatchers

A B budget variant on the 1950s an alien body snatchers film uncreditedly based on Robert Heinlein’s The Puppet Masters. Other films in this niche created great paranoid atmosphere but here the results only look cheap and tatty

Branded (2012)

Branded (2012) poster
Rating: ★★
Brand Names Revealed as Parasitic Entities

An ambitious film in its depiction of a near-future Russia and satire on the media. The latter half has the hero undergo a mystical experience and discover that advertising brands are living entities that feed on human need

Breach (2020)

Breach (2020) poster
Rating: ★★
Parasites Aboard a Space Mission

Another of the last films made by Bruce Willis, before his retirement. Here Bruce is on form and gives a decent performance. The film is an Alien copy with the crew of a space mission under attack by a parasitic lifeform

Dreamcatcher (2003)

Rating: ★★
Alien Body Snatchers/Stephen King Adaptation

Lawrence Kasdan directs an adaptation of the Stephen King novel about a group of men on a weekend get together in the woods who find themselves in the midst of an alien invasion

The 5th Wave (2016)

The 5th Wave (2016) poster
Rating:
Alien Invasion/Young Adult

Wannabe in the fad for Young Adult films. An alien invasion story that takes place without drama or engagement in anything that happens. This seems more interested in its teen love triangle than combatting the alien threat

Green Lantern: Beware My Power (2022)

Green Lantern: Beware My Power (2022) poster
Rating: ★★
Animation/DC Comics Superhero

Green Lantern is a classic comic-book character but his screen presence were damaged by the Ryan Reynolds film. This conducts a severe reset of the character’s continuity

Halo Legends (2010)

Halo Legends (2010) poster
Rating: ★★½
Compilation of Anime Shorts/Videogame Adaptation/Space War

A compilation of shorts from anime directors set in the Halo videogame universe. The first two episodes have a breathtaking scale but the others are bitsy stories but nothing standout

Hell Hole (2024)

Hell Hole (2024) poster
Rating: ★★★
Parasitic Monster

The Adams Family have been one of the most interesting creative talents in recent years – a family who perform all the functions on their films. Here they reinvent the Alien-inspired monster movie with highly entertaining results

Helldriver (2010)

Helldriver (2010) poster
Rating: ★★★
Gonzo Japanese Zombie Splatter

A mind-bogglingly wacky entry in the gonzo Japanese splatter film featuring a crazed bloodbath as Japan is overrun by zombies. This goes frequently nuts featuring vehicles and plans made up of zombie bodies

The Hidden II (1994)

The Hidden II (1994) poster
Rating: ½
Body-Hopping Alien

The Hidden was a wittily enjoyable hit about body-hopping aliens. This is a cheap sequel that substantially reuses material from the first film, while missing everything that made the original work

The Host (2013)

The Host (2013) poster
Rating: ★★★
Alien Body Snatchers

Andrew Niccol, a director of smart conceptual sf, seems mismatched on an adaptation of a Stephenie Meyer novel but Niccol tones down Meyer’s overripe teen romance to deliver a smart take on the alien body snatchers genre

Isolation (2005)

Isolation (2005) poster
Rating: ★★★
Parasitic Infections

Irish horror film about a series of deadly parasites amok on a rural farm. Playing like a serious version of the NZ comedy Black Sheep (but with cows), this has a grim, grimy atmosphere to it that does produce some undeniable effect

Jason Goes to Hell: The Final Friday (1993)

Jason Goes to Hell: The Final Friday (1993) poster
Rating: ★★★
Slasher/Mind-Control Parasite

The ninth of the Friday the 13th films and the most variant and fun of the series. This cheerfully turns expectations on their head and readily punctures the series cliches

Meatball Machine (2005)

Meatball Machine (2005) poster
Rating: ★★★
Gonzo Japanese Splatter Film/Bio-Mechanoid Creatures Battle

In the late 2000s, Japan has produced a series of films drenched in gore, featuring absurd creature effects and action moves; this was the first of them – a wonderfully cartoonish film with rival bio-mechanoid creatures fighting

Meatball Machine: Kodoku (2017)

Meatball Machine: Kodoku (2017) poster
Rating: ★★
Gonzo Japanese Splatter Film/Bio-Mechanoid Mutations

A sequel to Meatball Machine, the film that started the gonzo Japanese splatter genre, filled with wild mutations, over-the-top splatter, a surreal sense of humour and an obsession with schoolgirls in panties

Parasyte Part 1 (2014)

Parasyte Part I (2014) poster
Rating: ★★★
Body-Snatching Shapeshifting Parasites

Live-action adaptation of a manga about the war between body-snatching parasites that are capable of rearranging their host’s bodies. This plays out as a madcap version of The Thing relocated to a Japanese high school

Parasyte Part 2 (2015)

Parasyte Part 2 (2015) poster
Rating: ★★★½
Body-Snatching Shapeshifting Parasites

Parasyte Part 1 was a manga adaptation filled with wild effects sequences. This sequel is an even better film that expands the characters and ideas in quite fascinating directions

Phantoms (1998)

Phantoms (1998) poster
Rating: ★★★★
Evil Force Takes Over a Small Town/Dean R. Koontz Adaptation

One of the best and most underrated Dean R. Koontz adaptations, which creates eerie atmosphere out a town where the residents have disappeared due to what is revealed as a uniquely different creature

Planet Hulk (2010)

Planet Hulk (2010) poster
Rating: ★★½
Animation/Marvel Comics Superhero

Animated adaptation of the one of the biggest Marvel Comics event storylines of the 2000s – the same one also used in Thor Ragnarok. Essentially Spartacus recast with The Incredible Hulk

The Quatermass Xperiment (1955)

The Quatermass Xperiment/The Creeping Unknown (1955) poster
Rating: ★★★★
Mutating Astronaut

The first of the Quatermass films and the first major genre hit for Hammer Films. Nigel Kneale creates a literate work of science-fiction horror about a returned astronaut mutating after exposure to an alien fungus

Rabid (1977)

Rabid (1977) poster
Rating: ★★★
Parasitic Skin Graft

The fourth film from David Cronenberg, a clear (although by no means uninteresting) attempt to repeat the success of Shivers with Marilyn Chambers as a woman with a vampiric skin parasite that turns victims into maddened killers

[Rec]4: Apocalypse (2014)

[Rec]4 Apocalypse (2014) poster
Rating: ★★½
Zombie Outbreak on a Ship

The fourth film in the [Rec] series. This abandons the Found Footage look but without it, all we have is just another zombie film, nevertheless this builds to an intensively gore-drenched climax

Revealer (2022)

Revealer (2022) poster
Rating: ★★★
Stripper and Fundamentalist Trapped Together During the Apocalypse

This sells you with its concept – a stripper and a religious fundamentalist are trapped together in a peepshow as the apocalypse occurs – and works surprisingly well

Sella Turcica (2010)

Sella Turcica (2010) poster
Rating: ★★½
Mutating Gulf War Veteran

Horror film about a soldier returned home from conflict strangely ‘changed’ reminiscent of the classic Dead of Night. From the director of August Underground films.

Shivers (1975)

Shivers (1975) poster
Rating: ★★★★
Sexual Fetishism Parasites

David Cronenberg’s first commercial release, a vivid work about parasites that turn the residents of an apartment building into sexual fetishists. Cronenberg has set out to shock while beneath that he creates fascinating metaphors about sex

Spider-Man 3 (2007)

Rating: ★★★
Comic-Book Superhero

Last and by general opinion the least of the Sam Raimi-Tobey Maguire Spider-Man films. With three super-villains present, the plot feels as though it is bursting at the seams juggling the various origin stories and ongoing dramas, although Raimi still delivers some solid superheroic action scenes

Sputnik (2020)

Sputnik (2020) poster
Rating: ★★★½
Cosmonaut Returns Infected by a Parasitic Alien Organism

Strong intelligent SF film where a cosmonaut returns from a space mission with an alien parasite attached. On one level, not too different to a host of Alien copies but the difference is all in the approach

Star Trek II: The Wrath of Khan (1982)

Star Trek II: The Wrath of Khan (1982) poster
Rating: ★★★★
Intergalactic Adventures

Second of the Star Trek films, usually regarded as the fan favourite because of its often moving character focus on themes of life, death and aging. Ricardo Montalban makes a grandly theatrical villain and the film gets some great suspense out of space war sequences

The Tingler (1959)

The Tingler (1959) poster
Rating: ★★★★
Capturing the Spirit of Fear

The finest moment from gimmick master William Castle with Vincent Price as a coroner searching for a parasite that feeds on fear. Full of Castle’s luridly sensationalistic effects and containing the first portrayal of an LSD trip on screen.

Venom (2018)

Venom (2018) poster
Rating: ★★★
Marvel Comics Superhero

Anything with the Marvel Comics name on it is box-office gold. This spins a standalone film off from one of the main villains of the Spider-Man comic-book. This is watchable by several showstopping effects set-pieces.

Viral (2016)

Viral (2016) poster
Rating: ★★½
Plague Outbreak/Zombie Parasites

Effort from the near-ubiquitous Blumhouse that is constantly confounding expectations – a plague outbreak drama but not quite, a zombie film but not quite. In the end, not a great or groundbreaking film but certainly a modest one that takes things in some interesting and original directions

Zombie Ass: The Toilet of the Dead (2011)

Zombie Ass: Toilet of the Dead (2011) poster
Rating: ★★
Gonzo Japanese Horror/Zombie Ass Parasites

Completely insane gonzo Japanese horror that feels like it is made by a mad scat fetishist involving parasites that emerge out of people’s asses. The film is driven by its outrageously perverse imagery but for all that is haphazard and incoherent when it comes to explanatory rationale
