The 10 Scariest Giant Movie Monsters Of All Time

Published 5 years ago by , Updated August 28th, 2012 at 8:16 am, This is a list post.

Gwoemul The HostMovie monsters come in all shapes and sizes, and while some of the smallest creatures have produced the greatest fear in humanity, there's no questioning that the giant monsters that attack whole cities and engulf victims like Tic-Tacs are terrifying on a whole other scale (get it?). Movies have seen their fair share of the big fellas, and we've narrowed them down to those we think are the scariest of them all.Certain giant movie monsters just missed the cut, but came to mind while developing our 10 favorites. For instance, the Brain Bug from Starship Troopers is a massive and disgusting creature and the Graboids of Tremors are hideous creatures, but ultimately both missed our list.Don't forget monsters that don't quite fit the protocol, like the aliens from War of the Worlds or Independence Day. While their ships were massive and had the ability to destroy entire cities, the monsters themselves were "regular-size" aliens.One name that may instantly creep into your head throughout this process is King Kong. But we've decided he's just not that scary. Sure, a run-in on the streets of Manhattan might stop your heart, but after Peter Jackson's extensive humanization of the great ape, he's just not all that scary any more.Without further ado, let's get right into the scariest giant movie monsters of all time. SOME SPOILERS ahead as many of the films hide the identity until the last act.

The 50-Foot Woman - Attack of the 50-Foot Woman

Attack of the 50 Foot WomanNow this one is a gorgeous beast. It could be considered a subtle parody of the genre films of its era, but in 1958 Attack of the 50-Foot Woman was just downright scary on a number of levels.More impressive than the monster itself herself is the production budget of $88,000. Any monster movie that can accomplish its goal on such a microscopic budget deserves recognition. Either way, some would find a 50-Foot Woman to be the perfect monster, but it all depends on your perspective. If she stepped over you, your view might be better than if she stepped on you.The best part about the film is that it focuses on a specific problem. Instead of wreaking havoc on the world, the giant woman uses her new "power" to exact revenge on her cheating husband and his mistress.

Ants - Them!

Giant Ants from Them!One of the few monster movies that transcended its genre and entered the Oscar race, Them! was nominated for an award in the Special Effects category. In 1954, the giant ants of the film felt realer than any giant monster before. The tagline on a movie poster is just as hilarious as it is fear-inducting:
A horror horde of crawl-and-crush giants clawing out of the Earth from mile-deep catacombs.
That reminds me of the Graboids from Tremors, but much bigger and more threatening.The essential message behind the film came at a time when the nuclear threat was frighteningly new. The ants are mutated by atomic radiation to enormous proportions.Rather than immediately showing off the gigantic ants, our first glimpse is 30 minutes into the film. This is probably what sets it apart from so many monster movies of the time. It is about suspense and mystery. Once we uncover the clues behind the disappearing people, it becomes a scary monster movie with one of the best giant monsters of all time.

Mantis Creatures - The Mist

The Mist Mantis MonsterThere are so many monsters in The Mist that it could have a Top 10 list all its own. As the movie progresses, the monsters get bigger and meaner, ultimately finding a place on our list. One of the most intimidating creatures in recent memory has to be the giant mantis creatures that approach the cast near the end of the film.As difficult as it is to see the monsters in the thick mist, the sounds of their movement are just as scary. It's quite the moment when people are snatched into the sky or cars are crushed.

Stay Puft Marshmallow Man - Ghostbusters

Stay Puft Marshmallow Man GhostbustersOne of the funniest and scariest giant monsters of all time tears its way through Ghostbusters. There is nothing more frightening than an enormous multi-layered marshmallow with an attitude. But just imagine if you burnt the Marshmallow Man. That is one tasty monster.The history behind the Marshmallow Man is interesting. Wikipedia explains that in the original script, Dan Aykroyd was the person who thought of the giant marshmallow. It stemmed from the concept of a cute, cuddly mascot all blown up into a terrifying monster. Bill Bryan created the outfit as part of a miniature set which was blended in for the finished product.The worst part of a massive marshmallow man would have to be the sticky cleanup  left in its wake. How do you get towering pieces of marshmallow off a building? No easy task, that.

Tyrannosaurus Rex - Jurassic Park I-III

Jurassic Park T-Rex monsterIt's easy to argue the lack of size of the T-Rex. Its place on this list has more to do with its destructive behavior than its sheer size. But there is no question it is a giant monster. At nearly 20 feet tall and weighing eight tons, the T-Rex is a man-eating machine that spends the rest of its time destroying everything around it.The most relevant scene was its great escape in San Diego during the second half of Jurassic Park II. Starved and frustrated, the T-Rex roams the streets of San Diego, causing chaos and destruction. At one point, it throws a bus through a Blockbuster Video Store (which turned out to be a metaphor for the chain's future - who knew?).The signature roar of the T-Rex has become a staple in monster movies ever since. The roars of the Cloverfield monster bring back memories of our days watching disaster unfold in the first  Jurassic Park film.

Giant Squid - 20,000 Leagues Under The Sea

20000 Leagues Under The Sea monster posterWalt Disney had his own 1954 monster movie for the masses. While Ants! earned itself a single Oscar nomination, 20,000 Leagues Under The Sea actually took home a pair of Oscars for Art Direction and Special Effects, along with a nomination for Editing.The monster in 20,000 Leagues was terrorizing sailors before the film's story even got underway. But when the government sends Professor Arronax on a mission to find out if the giant sea monster truly exists, the film becomes a journey into the abyss.While the film ends up with only a brief encounter with the giant squid, it is one of the most memorable moments in the film. The main characters battle the giant squid and it becomes the cornerstone of the  action in 20,000 Leagues Under The Sea.The squid is a creature that deserved more screen time. With David Fincher's recently announced remake, we may yet get to see more of this beast.

Unnamed - Cloverfield

Cloverfield MonsterCloverfield worked mighty hard to hide the identity of the film's giant monster until the climax. Some were disappointed by the bizarre look of the creature, but there's no question it was one of the most intense monsters ever to take a swipe at New York City's skyline.The reason the monster is so effective has to due with the intention the filmmakers had for the beast. They have frequently discussed how the monster is not your typical rampaging beast - instead, it is like an infant, afraid of the world it has been thrown into and the small creatures (humans) attacking it. It tried desperately to escape, but couldn't maneuver the maze of streets and buildings in Manhattan.The monster definitely redesigned the look of the city, but it was mostly due to collisions and stumbling into skyscrapers. The only real time it seemed to knowingly attack was when it cut off the head of the Statue of Liberty.

Gwoemul - The Host

Gwoemul The HostSometimes a film is so good that it transcends its genre. The Host is one of the most acclaimed foreign films of the last decade and its beast deserves much of the praise. As Godzilla was Japan's cinematic allegory for the nuclear attack from the United States, The Host uses a fictional beast to incite satire for government occupation.A monster can metaphorically represent any number of things, but if it doesn't scare the hell out of its victims, it's worthless. The monster in The Host is so wild and unpredictable that it turns the film into a horror movie.It's more the presence of a hidden beast that creates fear and tension than its destructive behavior. The real question is whether its size is an issue; it's big enough to destroy bridges, so it is a relative giant.

The Kraken - Pirates of the Caribbean, Clash of the Titans

Pirates of the Caribbean The KrakenNo matter who fights The Kraken, you can always count on its massive scale. The enormous teeth threaten all who tread near its mouth, but that only matters if you can get that close. Most attacks from The Kraken occur on the open sea, but as shown in Clash of the Titans, it has been known to devour port city areas.Unfortunately for bystanders, The Kraken is just like any giant monster that takes  countless innocent lives. Yet, the one characteristic that makes The Kraken unique is that is must be summoned. In Clash of the Titans, The Kraken is released by Zeus. In Pirates of the Caribbean, The Kraken is summoned by Davy Jones. Yet even those in power seem to have limited control over the massive beast.The Kraken is one of the most deadly sea monsters around. If you can keep away from those in control of it, you should be fine on your voyages across the sea.

Godzilla - Godzilla

GodzillaGodzilla has gone through a number of makeovers throughout the years, but one thing remains certain - this giant lizard hates (almost) everything. While it has spent most of its "entertainment life" fighting other giant monsters, Godzilla has spent some time crushing cities and the humans in them.In fact, Godzilla is such a celebrity that he even has his own Hollywood star. He has experienced the glory days - from the original 1954 Japanese movie, to many, many subsequent films and television shows. But a 1998 adaptation by Roland Emmerich left the great lizard in shame, putting the well-known monster on the run for most of the film, instead of on the attack.Regardless, the devastation left behind when Godzilla arrives is nothing short of spectacular. To put it in perspective: the only man capable of bringing the beast back to the Hollywood spotlight was Roland Emmerich, King of Disaster Movies. There is no monster quite like Godzilla - that's why he takes the crown as the scariest giant movie monster of all time.P.S. - Stay tuned, because there may be yet another adaptation of the beast also known as Gojira - a Godzilla reboot movie that's due out in 2012.

  1. How the hell is King Kong not on this list?

  2. You forgot jaws, King Kong, the alien out of 8mm, war of the worlds… To name a few.

  3. Am I the only one that noticed that Gwoemul is a bit reminiscent of Tremors?

  4. The Killer Rabbit of Caerbannog in the movie Monty Python and the Holy Grail.

  5. “The Host uses a fictional beast to incite satire for government occupation.”
    What movie were you watching? The creature in ‘The Host’ was about, and the result of, pollution, over-fishing, etc. A classic humans don’t care about and ruin nature thing just like Godzilla.

  6. Marshmallow Man is definitely the creepiest thing exists… I can not explain, it just is insanely creepy!

  7. that is magmanimous, …

  8. I can’t believe you left the monsters in Alien/Aliens and Predator off your list! The Alien monster was truly terrifying; I screamed myself hoarse when the film first came out! STILL think it’s one of the best and scariest films ever! Predator wasn’t too shabby either, as cinema monsters go.

    • This is about GIANT monsters. The Xenomorphs in the Alien franchise, while certainly big, weren’t exactly on the giant scale.

  9. Jaws, cause he is real.

  10. I think Stay-Puft was goofy and destructive…not really scary. Take him off the list and put in the monster from Pan’s Labyrinth with the eyes on the palms of his hands…yikies!!!

    • Also…Darkness(the Devil) from Legend.

  11. In my opinion giant movie monsters are not particularly scary, I think the creature from “Alien” beats all hands down.

  12. whatever the demon was called from ‘The Keep’, proper evil and horrible, its just a shame the films hues are so dark

  13. How soon we forget a classic “Creature from the Black Lagoon” and as a swimmer, makes me think twice anytime I am in a lake, pond, or river.

  14. Horrible list… Yes these things are subjective but intelligence and common sense do also play a role, and this is absurd. A combination of old cliches added for the sake of being “classic” (even if not scary at all) and others simply ridiculous and I think named only so the author could feel they were being creative…I wish I had two more hands so I could give this list four thumbs down.

  15. Cloverfields Monsters name is: CLOVER

  16. I suspect that many have not seen this ” classic” ( so be it, Jack ) at all let alone in a theater. It was prefaced by a two minute intro by one of the main characters and was intended to frighten the audience, and it did.
    However, in a dark theater on a b/w screen the visage of the monster was horrifying. Of course, the movie was ” Frankenstein ” with Boris Karloff. It is second in remakes with 48 to ” A Christmas Carol ” with over 50. Why is that ?
    My vote for best scary movie, and this is a very difficult pick, is the first Alien. But alien was not a horror movie it was a sci fi movie.

  17. I think the Exocist girl Regan was the scariest monster of all.That scared the crap out of me.

  18. Im failing to see why any of these are remotely scary? 50 woman? Really?
    The Stay Puft Man? Er no.
    What about things like the Pale Man from Pans Labyrinth?
    Hellraiser Cenobites?

    I could go on all day but I cant be bothered. Just don’t think the writer has ever watched a horror movie.

  19. I have to say that the “Mist” was one of the spookiest movies I have ever seen. Fair to bad acting but you don’t really care. The exact Preying Mantis the monster mentioned here is exactly what would have picked. I don’t scare easy at all, but that stood out to me. Great movie!

  20. The Pale Man from Pan’s Labyrinth… that guy still gives me the creeps.

  21. You forgot the all time best. And that was “Alien.”
