Comic-Book Superheroes

After several other film incarnations that went nowhere, The Fantastic Four make their first appearance in The MCU. The film creates a wonderful retro world of 1960s futurism based on their original comic-books for them to inhabit

Comic-Book Superheroes

The 2005 Fantastic Four was an amiable entry among the Marvel Comics adaptations of the 2000s. This sequel substitutes lowbrow comedy and renders the great character of the Silver Surfer as a CGI cartoon

Fantastic Planet (1973)

Rating: ★★★★
Bizarre Alien Planet/Animation

The first film from French animator Rene Laloux, a trippily surreal vision and one of the few portraits of a genuinely alien world on film

Femalien (1996)

Femalien (1996) poster
Rating: ★★
Erotica/Alien Visitor

Work of softcore erotica about an alien woman who comes to Earth to catalogue human sexual experience. Consists of lots of tasteful glossily photographed tumblings with only the slimmest of plots connecting

The Fifth Element (1997)

The Fifth Element (1997) poster
Rating:
Space Opera/Showdown Against Ultimate Evil

A big-budget space opera from Luc Besson. This offers a dazzlingly designed future but the plot is an inane hodgepodge of bad SF elements with a tone that flails between action and camp

Final Days of Planet Earth (2006)

Rating:
Alien Invasion

Darryl Hannah is the queen of a species of body-snatching insects intent on invading Earth. This is a clear winner head and shoulders above any other contenders for the most ridiculous alien invasion work ever made.

Astronauts Discover All-Female Planet

One among a sub-genre of 1950s outer space sex fantasies where astronauts encounter all-women planets and sort them out with some good lovin’, Cat Women of the Moon is held as the Z movie of this genre but this is an even cheaper

Victorian Lunar Expedition/H.G. Wells Adaptation

Adaptation of the H.G. Wells novel about a Victorian journey to the Moon and encounter with its denizens. The film comes with Ray Harryhausen effects but is considerably weakened by a buffoonish tone

Victorian Lunar Expedition/H.G. Wells Adaptation

Very nicely produced BBC retelling of the H.G. Wells novel that conducts an extremely faithful adaptation of the story and captures a perfect period sense of wonder

Flash Gordon (1936)

Flash Gordon (1936) poster
Rating: ★★★★
Serial/Space Opera

The original and greatest of all SF serial adventures and a huge influence on George Lucas. Despite the primitive effects, this still has a marvellously rousing imagination that stands up today. Two serial sequels followed

Flash Gordon Conquers the Universe (1940)

Flash Gordon Conquers the Universe (1940) poster
Rating: ★★★
Serial/Space Opera

The third of the Flash Gordon serials, not quite at the heights of the previous two but with a colour and exoticism that was head and shoulders above the other serials of the era

Flash Gordon’s Trip to Mars (1938)

Flash Gordon's Trip to Mars (1938) poster
Rating: ★★★★
Serial/Space Opera

The second of the Flash Gordon serials, which relocates action to Mars following the popularity of Orson Welles’ War of the Worlds broadcast. The film has a wonderful imagination that far outshines the tattiness of usual serial production values

Flesh Gordon (1974)

Flesh Gordon (1974) poster
Rating: ★★
Softcore Flash Gordon Parody

This offers the amusing idea of a softcore parody of the old Flash Gordon serials. A surprisingly well-made film in terms of effects but the jokes often seems belaboured amid the witless mugging

Flesh Gordon Meets the Cosmic Cheerleaders (1991)

Flesh Gordon and the Cosmic Cheerleaders (1991) poster
Rating: ★★
Softcore Flash Gordon Parody

This sequel to Flesh Gordon, the R-rated parody of the Flash Gordon serials, feels like a joke that is belaboured in the retelling. The film does have a crass level of nonsensical absurdity that proves amusing

The Flintstones in Viva Rock Vegas (2000)

The Flintstones in Viva Rock Vegas (2000) poster
Rating:
Prehistoric Comedy/Cartoon in Live-Action

Sequel to the live-action The Flintstones film. Whether we asked for it or not, this offers up a Flintstones origin story where we see familiar elements of the series fall into place

Flying Disc Man from Mars (1950)

Flying Disc Man from Mars (1950) poster
Rating: ★★
Serial/Alien Invader

Twelve-chapter serial that offers one of the first ever depictions of an alien invader on screen. The results are oddly mundane in comparison to the onslaught of great 1950s alien invasion films that came only a couple of years later

Gonzo Exploitation Movie Homage

A beautifully shot b/w homage to exploitation films that feels like a 1950s rock‘n’roll musical injected with a host of gonzo elements including aliens, UFOs and the resurrected dead

Ghidrah the Three-Headed Monster (1964) poster

Alien Messiah/Cult Killings/Alien Abduction & Impregnation

Godzilla: City on the Edge of Battle (2018) poster

Anime/Japanese Monster Movie

The second of the anime Godzilla films and much more successful than its predecessor. The reconceptions of some of the classic monsters has a dazzling ambitiousness while Godzilla has all the ferocity it should have had in the first film

Godzilla: Planet of the Monsters (2017)

Godzilla Planet of the Monsters (2017) poster
Rating: ★★
Anime/Japanese Monster Movie

The 30th Japanese Godzilla film, this is the first anime Godzilla film and the first in a trilogy. More disappointingly, it is more a space opera and planetary adventure than it is ever a Godzilla film

Anime/Japanese Monster Movie

Japanese Monster Bash

The twelfth Godzilla film. Under director Jun Fukuda, a juvenile inanity had by now come to dominate the series by this point. The special effects, often recycled from previous films, are very cheesy

Godzilla vs the Cosmic Monster (1974)

Japanese Monster Bash

The fourteenth Godzilla film, noted for the introduction of Mecha-Godzilla, a robot copy of Godzilla that became a recurring nemesis. By this point in the series, the effects and quality of production had become very shabby

Goke, Body Snatcher from Hell (1968)

Rating: ★★★
Body-Snatching Alien Vampire

A thoroughly demented Japanese sf/horror film about passengers of a crashed plane being menaced by a body-snatching alien vampire. Quite unlike any other Japanese monster movie, the colour schemes alone leave you giddy

Horror Writer's Creations Unleashed

Marvel Comics Adaptation/Space Opera

Videogame Adaptation/Military Recruits in Training

Web-series, later released as a film, based on the Halo 4 videogame. While the games have a massively detailed backhistory of the universe, this is disappointingly only a low-budget military recruits in training scenario

Human Observers on a Barbarous Alien World

Adaptation of the Strugatski Brothers’ book about human observers becoming involved in the affairs of a barbarous alien society. Essentially a Star Trek Prime Directive story, the Strugatskis didn’t much like this version

Human Observers on a Barbarous Alien World

A modern cinematic masterpiece? A plotless three-hour work that rubs our face in the squalour of the Middle Ages while feeling like people crowded into a narrow room all trying to do cryptic things at cross-purpose

Heavy Metal (1981)

Heavy Metal (1981) poster
Rating: ★★½
Adult Animation Anthology

Cult animated film that adapts several stories from the adult fantasy comic-book Metal Hurlant/Heavy Metal. These vary but in its better moments that has a trippy cult hallucinatory quality

Heavy Metal 2000 (2000)

Heavy Metal 2000 (2000) poster

Adult Animation/Space Opera

Sequel to the animated Heavy Metal that failed to attract the same cult audience that its predecessor did. Telling only one story instead of several, it only offers a routine space opera adventure

The Hidden II (1994)

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

Bumbling Crusaders in Space

Roland Emmerich produced comedy about a group of crusaders abducted by aliens where their bumbling ends up accidentally winning a space war. A promising idea rendered as idiotic knockabout farce.

Rating:
Immortal Combat/Dark Future

Probably THE worst sequel ever made. The script’s treatment of continuity to the first film is utterly incoherent, while director Russell Mulcahy and most of the cast go at it with unrestrained OTT excess

Aliens Form Bluegrass Band

Aliens come to Earth and form a bluegrass band! The basic idea holds an undeniable appeal but the film seems caught between wanting to be a B-movie parody and an indie film that takes itself seriously

The Hitch Hikers Guide to the Galaxy (1981) poster
Rating: ★★★
Gonzo SF

The Hitch Hiker’s Guide to the Galaxy was a multi-media phenomenon that has developed a cult. The tv series with a less-than-stellar BBC budget was not the most effective incarnation of these but still hits the wittily absurd nerve of Douglas Adams’ humour

The Hitchhiker’s Guide to the Galaxy (2005)

Animation/Alien Visitors Comedy

An animated alien visitor film that is more likeable than anything suggests – it has a bubbly, juvenile pitch but generates a good deal of humour out of the alien fish of water amid human culture routines

Honeymoon (2014)

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

Romance with an Alien Visitor

Though the title seems more suitable to a book of pick-up lines, this is about a romance with an alien visitor set during the punk era. John Cameron Mitchell adapts a Neil Gaiman story but seems to have forgotten the comedy elements

Talking Alien Duck/Comic Book Adaptation

Android Takeover Plot/Alien Invasion

Alien Duplication and Takeover

Independents’ Day (2016)

Rating: ★★
Asylum Mockbuster/Alien Invasion

The Asylum’s mockbuster answer to Independence Day: Resurgence, a rehash of Independence Day on a cheaper budget. The desire to copy the title has forced some plotting oddities onto the film

Indiana Jones and the Kingdom of the Crystal Skull (2008) poster

Mass-Insanity Inducing Alien Substance

Alien Body Snatchers

Classic of the 1950s alien invader genre in which a young boy discovers that the adults around him are being taken over by Martian invaders. Director William Cameron Menzies makes striking use of sets to further a sense of alienation
