Atomic Age Monster Crab....Transhumanism?
Verified purchase
This movie is more interesting in concept than execution. Scene by scene this is a pretty generic monster movie of the period. But the broad plot is pretty awesome.

The titular crab monsters don't kill their victims per say, they absorb their consciousness. Their individual minds memories and personality continue on. Coreman worked with similar ideas in Night of the Blood Beast (1958) but in that film it was an alien threat positioned as more explicitly malevolent in it's assimilation, a sort of biological Borg. In this film the victims seem pretty chill about being part of a crab based gestalt now and keep trying to explain things to the human survivors. Who freak out and won't stop trying to kill the crabs. To be fair the crabs also forcibly 'upload' a few people but hey mistakes were made on both sides. It's like a First Contact situation gone wrong, but it's almost with ourselves.

This is all pretty heady stuff for a Roger Corman 1950's atomic paranoia B movie. I just wish these ideas were attached to a less cheesy production. I'd also love to know if we're intended to view the crabs as somewhat sympathetic. Because the humans never seem to discuss any of the implications, it's like they think they're in a normal monster movie. "Welp my friend is in a crab body now, gotta kill him.' Maybe at the time it just read like a metaphor for Communism. Probably that because the Crabs do a complete heal turn at the end and start talking about "planning an assault on the world of men" out of nowhere.

It's worth watching for fans of Coreman, sci-fi, monster movies, b-movies etc. Basically if you're the kind of person to be reading this review at all you should see this for historical purposes. But as a piece of entertainment taken at face value it's poorly paced, muddled, unfocused and a bit boring. I mean, it was on an episode of MST3k for goodness sake.

3 stars because I just didn't know what else to give this oddity of a film.

Giant snoring crabs...does anyone need this?
Verified purchase
Ohmygawd this is awful. Schlock isn’t this bad. You wait until like the last 15 minutes to see the actual crab monster, which is even more disappointing than the buildup. I won’t spoil it for anyone who hasn’t seen it...you owe it to yourself to watch it just to see how truly bad, bad can be. The sound fx are even awful. Whenever the crab is on the move it sounds like someone cracking crab legs at the Red Lobster. And you haven’t lived until you hear a crab snore...yes snore.
I finally made it though watching the entire film(I can only take it in small doses) and these are the main points: the professor could have saved Gilligan and the rest with a Morse code thingy which he apparently forgot on crab island, crabs love to burrow, crabs love to take on multiple personalities and stroll the beach at night and pinch off people’s hands, and low budget movie starlets point their ridiculously large gazongas at whatever danger is looming.
As funny as this all sounds, what’s painful is that the movie tries to ‘explain’ giant crab monsters scientifically. The actors try to be serious and treat it like they’re doing Shakespeare in the park and not a low budget B horror movie.
Just skip through to the last 15 minutes or so and that’s the very best of the film—which is super cringe-worthy. I feel traumatized it was sooo bad.

We Need All The Drawn Butter in the World

Radioactive giant crabs that not only eat your body but consume your mind as well.

Another great Roger Corman sci-fi horror movie. I love this, it’s a fun short movie. It is just the right amount of time to introduce your monster, let it eat through most of the cast, steal their minds, and then get dead. The ability to eat their minds and then have them talk to you was a really great feature and creepy as hell. Not only is it massive, almost unkillable, except when you need it to be, destroying the island you’re standing on, but it will eat your brain in the bargain. It’s full of science gobbledygoo and that also makes it so much fun. Through enough science sounding words into a script and bang you got a 50s sci-fi monster movie. I liked how Corman committed to a giant monster, instead of going to usual route with a normal sized model or even just a normal sized crab and superimposing it like most movies of the era. It looks cheap as can be but that is also part of the fun for me. It’s made out of plastic bags, builders foam and the sweat of the model builder and I love that handcrafted feel these old monsters have. Giving it human eyes was a great touch, something about those big eyes makes it more unsettling. I wonder if Guy Smith, author of the Night of the Crabs pulp horror series, was a big fan of this movie? A fun sci-fi romp my only question is why didn’t they try and drive the monster off with a big vat of drawn butter, crab’s natural enemy?

Not Corman's Best Nor His Worst
Verified purchase
This movie actually has a rather interesting premise. Giant, telepathic crabs that absorb the inner person of their victims.

Now that has just GOT to be original!

But about a third of the way into this movie, I found myself rooting for the giant, killer crabs to win...

The kindly Professor from Gilligan's Island here was a raspy, unlikable tough guy. The telepathic crab-brain voices were on the hokey side. The heavily over-used camera angle looking up the rocky side of a hill, yet calling it "the pit!" And the way the island was inexplicably getting smaller and smaller. (I think they did explain that last one, but I didn't catch it. Somehow the crabs were doing it, those rotten telepathic, giant crabs!!)

I thought the end of this movie was the best part. We finally get a good look at one of the giant crabs, and not just an arm telescoping into the field of view. And the cranky Professor finally redeems himself.

The giant crabs actually looked cool, so I'm adding a half star for that. Slick theater poster art, too. Real slick!

I was thinking that this film was OK to watch once, and that's about it. But now I want to go back and see why the island was shrinking. Oh, and I also subsequently bought a DVD set to get Corman's "War of the Satellites" (which I recommend), and this movie is also in that set. I have a feeling this film may grow on me a little when I do watch it again. Maybe I got too close to one of the giant crabs on my first viewing, and it absorbed a chunk of my mind. 🤔

2.5 STARS. Subject to change!

I thought that this would be some 'attack of the killer crabs' type of film where they had to fight off crabs. Instead, the crabs kill people and take on their personas and speaks and thinks too! That ruined it for me. They should have stuck to the basis. I just finished as I am type and I was almost dozing off while watching. Since it was short I figured that I should finished since I will never come back to it.

Side note, this had the professor from Gilligan's Island in it. I guess Hollywood saw him as a teacher or doctor type, since he played them a lot. Also, the lady in the film was sexy! I do not want to imagine what she looks like now - if she is still around, but she was on point then!

How Can You Crab About This Movie?
Verified purchase
For movies of this ilk, it had excellent production values: their was time and thought and money put into sets, there actors had a real script which they had read and they could act (mmmm), and the monster knew perfect English! He was a marvel! Now it's been pointed out that the crab was not all that he could be. Well, our first run in with him he decapitates a sailor(?)(he was supposed to have stayed in the boat). Then the crab becomes a cave dweller, and check out the size of those claws! He's mighty enough to create the island to have mini earthquakes causing bits, BIG bits to roll into the sea causing the island to very rapidly lose land mass.
Now he may not behave like a traditional crab, but he sure is alot of whatever he is. You've read the story line from other reviewers so I shall not be redundant. All in all, it's not a terrible movie. I had never seen a Roger Corman film before and now all I had heard over the decades now has meaning and now I get his style. You get what you pay for. And you could do alot worse. Enjoy the crab and be thankful the professor comes through in a pinch.

Roger Corman schlock

If you ever wondered what the Professor was doing before he was stranded on Gilligan's Island, he was giving his life to save others in a hilarious Roger Corman movie. This B&W Corman effort was probably one of his early efforts of low budget movies about monsters, and in this case, they were due to the radioactive tests of the 1950's, which was a common theme of movies back then. So expect terrible special effects, a very low budget, terrible scripts and some pretty bad acting. I mean what was that with the accent by the Jules character? This movie lacked some of the trademarks that were a Corman movie in later years.

A couple of seriously funny lines. ...dead, but voice and memory alive. And, ….once they were men, now they are land crabs. Don't expect anything to make sense. That was never the purpose of a Corman movie. Three stars because this was revisiting how movies in the 1950's were; like opening a time capsule. Oh, nothing in the movie was remotely like the cover art of the movie.
