Really Surprised!

Too much about the plot just didn't add up, the writing was bad, some of the scenes were cringey and awkward,

A movie that not only functions as a solid scarefest but a razor-sharp satire.

Through painfully honest and emotional moments, the movie becomes irresistibly relatable

This movie is quite cheesy and appears to be low-budget in most respects. In some shots the monster resembles a sock puppet, the exposition by the film's scientist is really lame, and much of the dialog is awful and predictable. However the monster revealed at the end as it attacks the woman and her daughter is actually pretty good, with antennae, eyes, jaws and legs that move realistically; the thing must have been operated by several technicians. I found that sequence similar in some ways to "Aliens" - the creature is somewhat similar in appearance to the alien "queen", and the woman even says something like "Close your eyes, baby" to her child when it appears they are going to be killed. The hero subdues the monster with a fire extinguisher rather than a flame thrower, but that's understandable given the low budget. I can't help but wonder if Cameron was inspired by this film.

The Monster That Challenged the World is a highly entertaining science fiction thriller from the fertile 1950s that retains its appeal many years after its initial release. The eponymous monster is actually a cluster of over-sized prehistoric mollusks that are released from their underwater slumber by an untimely earthquake. Predatory and surprisingly adaptable (despite their aquatic nature, the mollusks sometimes surprise their victims by sneaking around on land), the creatures threaten to turn all of nature on its head. Arnold Laven directs the picture with a sure and competent touch, and though the movie is certainly not blessed with a lavish budget nothing ever really looks cheap. The mollusks are surprisingly monstrous and scary looking, and several scenes are highly suspenseful, including an exciting moment when the lovely Gail (played by Audrey Dalton) and her daughter are cornered by a rogue mollusk that won't be deterred by barred doors. Acting is solid all round, and while Tim Holt is a somewhat unconventional leading man he plays the role of the no-nonsense but kind-hearted soldier well, and his romance with the attractive Gail is realistically developed. I can't vouch for the science in this science fiction movie, but the rationale behind the mollusks' re-emergence and the threat they pose to the world is plausibly written within the context of the script. The story moves swiftly with a satisfying climax. Not as famous as some other monster hits from the 50s, The Monster That Challenged the World is actually one of the best of its breed and is still a great way to spend a lazy weekend afternoon.

"The Monster That Challenged the World" is one of the many 1950s sci-fi flicks about giant monsters attacking everyone. In this case, it's giant mollusks. Naturally, it's a really fun movie, if completely absurd. The substance that the monsters spew appears to be melted marshmallows, and the first time that one of the characters came across the substance, I thought of "Somebody blows their nose and now you want to keep it?" from "Ghostbusters".I noticed that one of the cast members is Hans Conried, better known as the voice of Snidely Whiplash on "Rocky & Bullwinkle" (he also voiced Capt. Hook in Disney's "Peter Pan" and played a wayward pilot on "Gilligan's Island").Anyway, a really cool movie. Must have been fun to make.

This is one of the many movies that were made in the '50s featuring "giant" prehistoric creature. Out of the bunch, this is quality made, and is a good movie to watch even today.The acting is good in this movie, and it's not about men standing around and philosophizing over what to do as many of the movies of this type are. There's real story, and monsters appear when you want to see them. Suspense and intrigue is palpable, and just when you think the story is coming to an end, there's the second cliff hanger.This movie was popular back in the '60s as reruns on TV. It was a good watch back then, and it still holds its quality over the years. A very rare case for '50s B sci-fi movie.
