O Monstro que Desafiou o Mundo

This rates up there as one of the better "giant monsters wreak havoc on mankind" movies that came out of the 1950s. The predators this time are overgrown snails/mollusks/caterpillar-like creatures that awaken from the pits of the Salton Sea after an earthquake shakes things up and charges them full of radiation. These monsters may appear of the dime store variety to those who aren't used to these "big bug" pictures, but actually they're pretty believable for a movie like this. Some of the assets setting this feature apart from its relatives would be the serious treatment of the story, some good acting and characters (it's fun watching Hans Conried as the knowledgeable scientist), and a few impressive pre-JAWS ocean scenes (one of the female victims meets a fateful watery demise, for example). Also adding to the effectiveness are some creepy ravaged corpses, the likes of which weren't usually this prominent back in the day. *** out of ****

The Monster That Challenged the World is about some prehistoric molluscs who were in some dormant eggs that got themselves hatched. They are spreading death and destruction through their abilities to come out on land and feed, usually on unsuspecting humans.

The special effects are a might better than some of the science fiction cult classics from the Fifties. The story does bog down a bit in the personal part. Tim Holt's character is introduced to us as a by the book navy commander who softens with no real reason why.

When he did this film Tim Holt had been off the screen for five years after the B picture western disappeared from the big screen and on to television. Why Holt didn't go the way of television in his career is a mystery.

Tim Holt had one of the strangest careers in Hollywood history. He was a very good actor, gave good performances in both western and non-western films like The Treasure of the Sierra Madre, Stella Dallas, Stagecoach, My Darling Clementine, and The Magnificent Ambersons. Yet he consistently went back to doing B westerns for RKO. His westerns were above average in the B film market, but they did nothing to advance his career. Another guy who replaced Holt in B westerns at RKO went on to a mega career, that being Robert Mitchum.

So in 1957 while Mitchum is doing critically acclaimed stuff like Heaven Knows Mr. Allison, Tim's doing The Monster That Challenged the World. Insisting on being a B picture cowboy finished him for anything else. So sad.

Holt did do two subsequent films that I've not seen, but the description makes them sound worse than this one.

You can watch The Monster That Challenged the World and still enjoy it. But if you liked Tim Holt and his screen performances and persona you will have a twinge of regret.

An earthquake out in the Salton Sea awakens the creeping dread, gigantic vampire water snails are on the loose and they are hungry for human fluid!.

Just about the right side of good, The Monster Who Challenge The World holds up well because of it's well constructed creatures and a bit of care and attention to the boffin discussions. Far too many 50s creature features just used a basic premise of creatures obliterating mankind because they were in an odd mood, but much like The Beast From 20,000 Fathoms, this picture at least takes time to give us a bit of a nature heartbeat to help us understand the methods of a mollusc, and that alone should be applauded, learn while we have fun so to speak. The cast ooze B-movie standards, and that is in no way a bad thing here, whilst the Catalina Island locale sequences are pretty nifty to help salt the beef as it were!

Good honest fun that isn't short on creepiness, and top marks to the makers for introducing a very ingenious creature to a truly wonderful genre. 6/10

Of course The Monster That Challenged the World is slowly paced. With a budget of about twenty dollars there's a lot of filler. But what little budget there is, is well used in creating a great animatronic monster.

The story is basic but well-structured and it works. I can watch this one over and over without wanting to throw things at the screen or yell at the characters for doing stupid things. My intelligence is more seriously insulted by modern horror films and their idiot protagonists than it ever is by The Monster That Challenged the World.

Among low-budget sci-fi flicks of the 1950s, The Monster That Challenged the World ranks near the top!

I found this film about giant snails on the loose in the Salton sea area slightly better than most programmer monster films of the late 1950's. The giant snails are a believable menace in that they are presented as no more dangerous than any other large aquatic predator such a shark or crocodile. They put a fight but can be killed with several well aimed shots from a pistol or a heavy axe. The real danger as pointed in the film, is that snails are extremely fecund, and if they were to enter the ocean , they could reproduce in enormous numbers thus creating ecological havoc. Anyone who has ever had a fish tank knows once you introduce one tiny snail, in a matter of couple of weeks you have hundreds. One odd aspect everyone seems to comment on is that snails look like caterpillars in snail shells. There is a type of aquatic insect larva that uses a discarded snail shell as armour, much like a hermit crab does. Perhaps someone involved with the film had seen these insect larvae and mistook them for snails.
