According to George Romero, this film about aliens inhabiting dead bodies to take over the Earth, was one of the main inspirations for 'Night of the Living Dead'.
The aliens when not inside a dead body, remain invisible throughout most of the film and wreak a good bit of havoc. They cause plane crashes and other disasters, which create fresh bodies for them to use and in one instance a zombie interrupts a hockey game by invading the announcer's booth in order to broadcast their demands.
'Invisible Invaders' turns up occasionally on both the AMC and TCM movie channels and is worth watching.

This film is very difficult to find. As far as l know it has never been released on VHS or DVD. I can't say it scared me when I saw it a kid, but it did leave some vivid impressions on my mind.
A pair of aliens take over the corpses of two scientists, a man and a woman. For about half of the film, the male scientist is missing his left arm, all he has is a bloody sleeve where his arm should be. The aliens set up shop in a cave near Cape Canaveral and every time a rocket is launched, the male alien goes outside and shoots it down with a ray gun type rifle.
It's interesting to note that during the course of the film the dead bodies that the aliens inhabit do show increasing signs of decay, but nothing really spectacular or grotesque. Although this may seem like an interesting film to try to locate, a word of warning ... this was made by the same people who did the infamously awful movie 'Robot Monster' and both films have the same level of script writing, acting and special FX.

A mad Nazi scientist comes up with a way to electronically control dead bodies with surgical implants in their brains. He can remote control them like robots and see what they see on a TV monitor in his lab. Soon gangsters take over and start using rival thugs and a police detective they've killed, as robotic zombie crime slaves.
This film was written by Kurt Siodmak who wrote the screen plays for many Horror and Sci / Fi films of the 1940's and 50's including classics like 'The Wolf Man' and 'House of Dracula'.
While this is an extremely low budget piece of work, it's hard not to like a film with dead gangster robot zombies. There is no gore, but the climax is pretty cool, with a battle between the zombies and the police. Definitely an entertaining movie!

In the late 1970's "film critic" Micheal Medved wrote a film guide which dubbed 'Plan 9 from Outer Space' the worst movie ever made. This caught the public's imagination and the film soon became a cult classic. I can think of a dozen or so films that have come out since then that are far worse and with bigger budgets too.
'Plan 9' is no worse than many other low budget films of that era. Stephen King once said that he could not understand how anyone could laugh at a film that horror legend Bela Lugosi died while making.

The working title for 'Plan 9' was 'Grave Robbers from Outer Space' and this line is used in the film's prologue. The plot concerns aliens who are angry about our nuclear bomb tests. They revive some dead people and use them as zombie tools of distruction. Tor Johnson and Mala Nouri aka Vampira play the two main zombies and their images as these characters have become quite well known even to non horror fans.
The film does have it's moments of unintentional silliness, but it is not nearly as bad as many people have been led to believe.
if you enjoy low budget 1950's horror films, give this one a look

The most note worthy thing about this movie is that it has always been available on VHS at nearly three or four times the cost of similiar films! I once had a discussion about this with the owner of a video rental store, who also was a horror film buff. The only conclusion we could come up with is that at one time 'The Zombies of Mora Tau' was a very popular cult film.
Unfortunately this is a movie that has a very good premise, but nothing else. 50's scream queen Allison Hayes and a cast of veteran B-movies character actors try there best to overcome cheap, unconvincng cardboard sets and terrible production values ... even for this type of film.
It does provide one or two unintentional laughes, but hardly worth wasting your time or money on. TNT used to run it on their Monstervision program, or you can buy it from Amazon where it currnently sells on VHS for $59.99 !!

Although not a zombie film in the true sense of the word, this is another of the films often mentioned as an influence on 'Night of the Living Dead'. The 1990 film 'Jacob's Ladder', also borrows heavily from it's plot

The fact that this was an independently made low budget film, helps the look of the film and the use of non actors in some minor roles gives it an authentic feel making the horror segments all the more surreal and dream like.
There are four DVDs of this available. Two cheap double feature ones that feature as the second movie either 'Dementia 13' or Horror Hotel, a regular single release and the 'Criterion Collection' editon which has these features and extras.

• Commentary by screenwriter John Clifford and late director Herk Harvey (on Disc Two, extended director's cut)
• Theatrical trailers
• Contains both the original theatrical version (78 min.) and the extended director's cut (83 min.) on two separate discs.

• Luminous new digital transfer of the original theatrical version of the film
• The Movie That Wouldn't Die! The Story of Carnival of Souls, a documentary on the 1989 reunion of the cast and crew
• More than 45 minutes of rare outtakes accompanied by Gene Moore's organ score
• Theatrical trailer
• An illustrated history of the Saltair resort in Salt Lake City
• The Carnival Tour, a video update on the film's locations

• The extended director's cut of the film
• One hour of excerpts from films made by the Centron Corporation, an industrial film company based in Lawrence, Kansas that employed Harvey and Clifford for over 30 years
• An essay on the history of Centron from Mental Hygiene, Ken Smith's new book on industrial and educational filmmaking
• Tom Weaver's printed interviews with Harvey, Clifford and star Candace Hilligoss, illustrated with vintage photos and memorabilia

I Highly recommmend this film, even in the cheaply released and edited DVD and VHS versions

I Eat Your Skin
1964 B&W

This film was made in 1964, but not released until 1971 when it was double billed with 'I Drink your Blood', on the drive-in movie circuit.
Most reviews of this film mention that no skin is actually eaten and I'll add to that nothing much else happens either.
Some doctor on some tropical island is trying to find a cure for some disease by experimenting on some natives or something along those lines. It's such a boring film that I lost interest about ten minutes into the story. The natives become zombies due to the doctors medical testing and this causes their faces and arms to appear to be covered in oatmeal. Their eyes also turn into ping pong balls.
If you're having trouble falling asleep, pop this in the ol' VCR and you'll quickly doze off. I doubt that even a showing on MST3K could help this movie.

The Last Man on Earth
1964 B&W

This Italian made film is the first adaption of Richard Matheson's novel 'I Am Legend'. It stars Vincent Price and is much closer to the orginal story and in my opinion, much better than 'The Omega Man'. It is also the one film listed here that comes closest in look and feel to 'Night of the Living Dead'.
However, the "Living Dead" in 'The Last Man on Earth' are treated more like vampires, they are repelled by garlic and are killed by impalement.
This film is now available on DVD and is one I feel belongs in any horror collection.

Plague of the Zombies
1966 Color

People begin to die mysteriously in a small community in Cornwall and are then seen around an abandoned mine. A new doctor comes to town and begins to suspect black magic is the cause of it all.
This Hammer Studios entry into the Voodoo / Zombie genre is up to their usual standard of quality. Good acting and atmosphere.
This film was available on VHS from Anchor Bay and it may have been discontinued. Several people have mentioned finding it along with other Anchor Bay releases of Hammer horror films in bargain bins or at reduced prices.
If you enjoy other horror films by Hammer, such as their Christopher Lee Dracula series, then you will want to see this film.
