A Masterpiece!

The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

It's entirely possible that sending the audience out feeling lousy was intentional

The film makes a home in your brain and the only cure is to see it again.

TWO LOST WORLDS is an amusing little adventure flick made on an obviously low budget. The story is about settlers versus pirates, with strapping James Arness the hero of the hour who spends most of his time in a love triangle with a pretty magistrate's daughter and her ranch-owning lover. The film has a low rent but exotic feel to it with a light, action-focused plot to keep youngsters entertained. Late on in the proceedings, the heroine is kidnapped by dastardly pirates and taken to a 'lost world' inhabited by erupting volcanoes and dinosaurs. The dinosaur footage is brief and ripped off from earlier films and features a couple of lizards with glued-on fins fighting. High art this ain't, but old B-movie fans will get a kick out of it.

American sailor has his ship attacked by pirates and ends up ashore in Australia where he falls in love with one of the local women. When the pirates attack the village the sailor has to go off to rescue his lady love...only to end up shipwrecked on an island with dinosaurs.Misbegotten adventure film that stands out only because of the dinosaurs in the final minutes, this is a clunky adventure film that isn't very good. One person here on IMDb indicates that this is actually several episodes of an an sold TV show stitched together, which makes perfect sense owing to the compartmentalized structure of the films stories. Not really bad, it is like watching an old TV show that you never heard of for a good reason. I picked up the film because of the dinosaurs on the cover only to later read about how they only show up at the end, and then was shocked at how little even that was. My dislike for the film has nothing to do with the lack of monsters, indeed I was ready to bail on the film early on, but kept going because I wanted to see said beasties.Not worth your time, let alone your money

During the 40s and the 50s many sci-fi and adventure movies were produced about giant monsters fighting brave adventurers. "One Million B.C." (1940) is probably the best known example and the one that started the trend, but there were many low-budget films that tried to emulate the success of that film with less than spectacular results. "Two Lost Worlds" may be one of those lesser known films, but what makes it "different" from the rest is the fact that it contains basically every element of the action-adventure sub genre to tell its story. From pirates to dinosaurs, and from naval fights to cowboys, this one has it all.James Arness is young Kirk Hamilton, a brave captain who is severely injured after being attacked by pirates on their travel to Asia. While his ship continues the trip, he is left in Queensland, Australia to recover, where he'll find the beautiful Elaine Jeffries (Kasey Rogers) and her precocious sister Nancy (Jane Harlan), as well as earning the enmity of Martin Shannon (Bill Kennedy), a man who is also in love with Elaine. But adventure calls him even there, as the pirates return and raid Queensland, kidnapping Elaine and Nancy and taking James and Martin to adventure. In their rescue trip they'll fight not only the pirates, but the strange creatures of a nearby island.Well, this film is basically an epic adventure that includes basically every element necessary to be classified as "adventure". While this is indeed as messy as it sounds, it has an explanation: "Two Lost Worlds" was made of two episodes (maybe three) of a failed TV series project blend together to work as a B-Movie. The origins of the film are very notorious, as the movie changes of "theme" as it changes of setting (aided by some rather poor use of stock footage), as the film goes from one adventure to another the pace feels at times disjointed and the constant narration doesn't help to make it better.The movie's most notorious "detail" is the use of the famous footage "One Million B.C.", and while it is in fact sold as the hook of the film, the actual scenes used are rather short (due mostly to the previously discussed factors). Technically, the film is rather poor and it probably would had worked a lot better as a TV show (as it was intended). This was director Norman Dawn's final movie after directing a long series of adventure movies, some of them rather infamous like "Wild Women" (1951) and "Tundra" (1936).If there is a redeeming feature in this movie (and one that's worth a lot), is the acting. A pre-"Gunsmoke" James Arness carries the film with grace and makes charming a character that otherwise would be poor and stereotypical. Kasey Rogers (who would participate in an iconic scene later that year in "Strangers on a Train") is equally effective although her character may be "too 50s" for today's standards. Bill Kennedy is also good as the Kirk's rival and has very good scenes (his character was probably the most developed of the cast).It would be easy to point out the many problems of "Two Lost Worlds", but one has to consider that it was a low-budget production (for TV) on a time where special effects were a novelty (it wasn't the only movie to use ""One Million B.C."'s stock footage) and while this is no excuse for its disjointed storyline, the film is considerably more enjoyable than most films of its era."Two Lost Worlds" is by no means a classic. It may not even be a good movie. But at least it entertains, and for most movies that's something. People looking for classy horror and adventure better look elsewhere, those interested in a strange novelty and/or the career of a young James Arness will find "Two Lost Worlds" an interesting piece of film. 5/10

Two Lost Worlds is more of an adventure movie than a sci-fi but I still quite enjoyed this.After being attacked by pirates, the clipper ship The Queen settles in Queensland, Austrlia while its captain recovers from injuries received during the attack. He falls in love with one of the local girls there and pirates then raid the colony and they escape. After the ship is attacked again and set on fire, the few survivors end up on an uncharted island where they encounter dinosaurs and then a volcanic eruption and earthquake and are then rescued.The dinosaur footage in this movie is the fight from One Million BC, as is the disaster footage, where we get to see more enlarged lizards from that movie too.The only member of the cast I've heard of in this is James Arness (The Thing From Another World, Them!).Despite the low budget, Two Lost Worlds is worth watching. Not bad at all.Rating: 3 stars out of 5.
