One of several remaining members of its race, an alien from Venus is guided to Earth by disgruntled scientist Tom Anderson, who tells it which humans it should attach mind control devices to. Among them is his old friend, fellow scientist Paul Nelson. Nelson, after killing a flying bat-thing which carries the device, finally persuades the paranoid Anderson that he's been wrong to ally himself with an alien bent on world domination. They hurriedly leave when they discover Tom's wife has picked up a rifle and gone to the alien's cave to try to kill it. Written by Doug Sederberg <vornoff@sonic.net>

In the beginning of the movie when the satellite is launched, the camera rolls back to reveal more of the control room. As it does, you can clearly hear the squeaky wheels of the camera dolly. See more »


Dr. Tom Anderson: Do you have any idea what you're listening to?
Paul Nelson: London Philharmonic?
Dr. Tom Anderson: It's Venus.
Paul Nelson: Uh-huh.
Dr. Tom Anderson: Venus.
Paul Nelson: Why not? We've bounced signals off the moon's surface. There's no reason that Venus shouldn't radiate impulses.
Dr. Tom Anderson: No, I don't mean the static. Can't you hear it? The other thing?
Paul Nelson: ...What other thing?
Dr. Tom Anderson: Listen to it, Paul! Listen to the voice!

Alternate Versions

Australian DVD released by Siren (which features "Creature From The Haunted Sea" on the same disc) is taken from an old print which for some reason omits nearly every shot of the monster, leaving many scenes near the end totally incomprehensible. See more »

In spite of the ridiculous, cucumber alien monster (which is fortunatedly kept off-screen through most of the film) this is actually an intelligent science-fiction thriller that's very much in an OUTER LIMITS vein.

Misanthropic scientist Lee Van Cleef makes contact with a being from Venus who promises to save mankind from his own self-destruction. Cleef paves the way for the alien to come to Earth, where it hides out in a hot springs cave outside of a small, remote Southern Californian town. Upon arriving, the being (or should I say invader) proves to have sinister plans of its own.

This early Corman quickie is quite good as long as you're not evaluating it based by today's high-tech standards. It's naive and unsportmanslike to condemn a film just because it was made decades before CGI was even invented.

The film has a certain disquieting mood about it. The remote setting adds to the sense of paranoia and isolation, and though the plot is sometimes critizied as being awkward, that tells me that the critic may be a short attention span member. You need to put some brainwork into your film viewing if you wish to gain any savory qualities from it. Whining because a planet isn't exploding every other minute is very superficial, and true science-fiction isn't for the shallow non-thinker who only has instant, immediate gratification on his non-mind.

A subtle sense of terror builds throughout (similar to INVASION OF THE BODY SNATCHERS) as nearly the entire cast meet unspeakable fates. The story carrys a pertinent cautionary message: Blind devotion to a utopian ideal can lead to the worst kind of disillusionment and tragedy. History has taught us that many times over. Science-fiction is meant to be provocative and not just shallow, forgettable entertainment.

Sure, if this film had a higher budget, and perhaps a little more script polishing, it could have been one of the top fifties science-fiction films. As it is, it's interesting with intriguing possibilities, and as long as YOU haven't been taken over by high-tech effects and sales hype, you may find it worth taking a look at.
