n my opinion it was a great movie with some interesting elements, even though having some plot holes and the ending probably was just too messy and crammed together, but still fun to watch and not your casual movie that is similar to all other ones.

The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.

The acting is good, and the firecracker script has some excellent ideas.

Actress is magnificent and exudes a hypnotic screen presence in this affecting drama.

Those poor monitor lizards forced to fight with attachments glued on them. With god knows what type of paint used I fear they did not fare well when the shooting was complete. If you can sit through this long enough to see the "dinosaur" fights you'll see what I mean.This movie is hysterically bad.Along with the obvious misuse lizards is the stereotyping of the natives and their simple speech and that make this movie the cultural milestone it is not. Unless you are high and want a chuckle at bad effects and rubber dialog do not waste your time with this one.

While I'm a fan of adventure fantasy as the next nerd, unfortunately, a sci-fi picture like "The Lost World" has a plot that has become shopworn and a bit too familiar (watch numerous Irwin Allen shows from the 60s, like "Voyage to the Bottom of the Sea" or "Lost in Space" for reptiles "disguised" as dinosaurs, and the plot of this film is almost copied to the point of scenes practically being identical to that of an episode of "Voyage" in its First Season) to have the kind of resounding effect it might have had for kids back then. A group of characters (like a professor played with bluster and gruff by the wonderful Claude Rains and the dignified and proper Michael Rennie as wealthy hunter, and the usual assortment of colorful tag-alongs, like David Hedison (who would go on to star for Allen in "Voyage"), and curvy Jill St. John as the love interest that seems to come between Hedison and Rennie) pursue the location of a "hidden" world where prehistoric dinosaurs still exist, finding a lot more than they bargained for.Diamonds, lava-flowing volcano eruption, cave-ins, a tribe with spears ready to sacrifice, and giant lizards—oops, dinosaurs all offer dangers to the cast. Included is the smokin' Vitina Marcus as a tribe babe (with a tan to die for) the group encounters and brings into the fold, character actor Ian Wolfe (he's been in a little bit of everything) as the blind, lost scientist Burton White, Richard Hadyn (the Twilight Zone episode "A Thing About Machines" and "The Sound of Music") as the hapless, always-embarrassed professor who accompanies them and often played as a comic foil, & Ray Striklyn and Fernando Lamas, both sketchy and perhaps not to be trusted (Lamas is amusing as the local who offers salutations to the group once they arrive to the jungle prior to traveling into the lost world). With diamonds, greed could motivate a gun from its holster and pointed at people.Marcus seems to be in the film merely as eye candy, and I must admit that it was hard to pay attention to anything else going one when she's bandying about in such a skimpy costume of such barely-there rags. I can only imagine how cool this could have been if Willis O'Brien had been hired for stop motion effects instead of the laughable lizards used as fake dinosaurs that are very unconvincing. The Lost World, in widescreen color, looks every bit the large sets on a Fox lot. I felt like I was watching a television show of "Voyage" expanded to 90 minutes. Still, seeing Rains brushing annoying people aside that get on his nerves (at one point, knocking Hedison to the ground after leaving his plane!), and Rennie every bit the stoic gentleman (on screen) are fun to watch in the same film together. While Jill St John is stuck with the gold digger part, pursuing Rennie, thankfully she's likable enough to flesh out her character a bit (these kinds of films often feature the stunner with the well-manicured pet who has no business participating in a grand adventure that requires a tolerance for the outdoors, sweat, dirt, and monsters). Dinosaurs fighting with their tails threatening Hedison and St. John who try to keep from plunging off the side of a mountain and even the large flowers that open and close on humans who walk within them ("Lost in Space" fans will recognize this), Irwin Allen wasn't about to let such scenes and sets go unused after this film. For a Saturday afternoon, in need of an adequate adventure to waste some time on, "The Lost World" could do the trick, but I have seen "Voyage" episodes from the first season that are just as good.

Based upon Arthur Conan Doyle's famous novel, this film really avoids the book. Filmed three and a half decade after the first 1925 version, the director Irwin Allen avoids the the book, not slightly but too much and I think that caused a failure of this film.This film has a brilliant acting crew, I mean Claude Rains (always brilliant, unforgettable and distinctive in his performances, but, I think he didn't care to much for his character, I guess he was payed and that's it, he didn't do much with his character), Michael Rennie, Jill St. John, David Hedison and Fernando Lamas... but no luck from them either. The movie "set", where they were filming was so fake, that I wouldn't take a leak there. Special effects? Where? They masked lizards and edited them on big screen to look more intimidating, that's it, I think that lizards didn't feel to good...But, the main thing is that these stories about lost worlds, and other remote places in which evolution didn't occurred, filled with all kinds of degenerate creatures are extremely old, even today. Today? Those stories are long dead on big screen. Well, except maybe for King Kong (2005), but that was remake. No matter how you try, these kind of stories, if you want to put them back on big screen, than you must adapt it to the modern audience. But, again... who would watch that?

I just saw this 1960s version of The Lost World and I must say it's pretty amazing! It's like the Jurassic Park of the 1960s. In the movie a professor in London England decides to prove his theory about seeing dinosaurs in a Lost World by taking a group of explorers on an expedition to the Lost World where they not only find dinosaurs but a group of Natives as well! The dinosaurs I thought were just wonderful! I was just blowing away with them and the actors and actresses gave wonderful performances. I think Sir. Arthur Conan Doyle who wrote the novel of the same name would of been pretty proud of this film adaption of his novel! It's a true dinosaur classic 10 out of 10!
