    Precursor to The Valley of Gwangi

    This movie is scripted by Willis O'Brien ,who obviously thought so much of it ,that he used it again in 1969 for the superior The Valley of Gwangi It is a curiosity among movies, being a science fiction and Western hybrid .Mexican based rancher Jimmy -woodenly played by Guy Madison -believes that his dead cattle are the result of predators .He is thinking "Mountain lion " or "coyote " maybe .Wrong!Its a T-Rex and the pattern then follows the standard monster movie template -capture and escape ,rampage and eventually happy ever after resolution . The monster effects are okay for the era but completely overshadowed by the genius of Ray Harryhausen ,employed in the remake .Add somewhat muddy colour and you have a movie whose technical side is deficient by today's standards It still remains worth watching however if only for its being such a rare commodity in combining monster movie and Western

    Too long.

    First of all, I don't know why this site says this movie is Horror, Romance, Sci-Fi. It's not any of those. It's a light-hearted western comedy. If a man failing to steal a woman is a romance, then this is a romance. I haven't seen many westerns but from what I have heard they all have this plot. The bad guy wants to chase someone off their land. And there's a drunk Mexican. The only really bad thing about this movie is that it is way too long. There are several extended periods of nothing and it's hard to keep paying attention. Basically, this movie is a family friendly monster flick that no child would ever have the patience to sit through. I'm sure if you could force a first grader to watch the whole thing, they might thing it was awesome. A second grader would know better.

    This is one cattle rustler they won't hang!

    Just a little south of the Texas border, the cattle ranchers are having trouble with an unusual rustler -- a Tyrannosaurus Rex. This is one of the few non-Harryhausen stop-motion films produced during the 1950s. The original concept was bought from Willis O'Brien by Edward and William Nassour, but they reneged on their promise to hire O'Brien to do the animation. The Nassours did it themselves. The animation is extremely rough, but the model of the tyrannosaurus is pretty good (except for its excessively long tongue -- it looks like a long red tentacle!)

    Be prepared for a long wait before the dinosaur shows up; the first two thirds of the film is pure Western soap opera and endless filler scenes of a Mexican fiesta. The dinosaur doesn't actually make an appearance until the last twenty minutes of the film. The climax, however, is action packed -- a running battle on the open range between a hungry dinosaur and the cowboy hero, Guy Madison (star of TV's `Wild Bill Hickok' from 1954 to 1957). Patricia Medina is the lovely heroine.

    Watch for a scene in which the tyrannosaurus runs after a galloping horse; the animation was done with a series of plaster models, each one posed at a different point in the running reptiles stride. Special effects processing was handled by Jack Rabin and Louis DeWitt (`Kronos' and `Atomic Submarine').

    TRIVIA NOTE FOR TRUE SCI-FI FANS: The T-Rex in this movie is just one of many sci-fi monsters that were defeated by actors who achieved fame in cowboy roles. In `Tarantula' the spider is destroyed by a bomb dropped by pilot Clint Eastwood. The Martians in `War of the Worlds' are pitted against Gene Barry, star of TV's `Bat Materson'. The ants in `Them' are gunned down by James Arness of `Gunsmoke'. `The Beast from 20,000 Fathoms' dies from a radioactive bullet fired by Lee Van Cleef, star of `The Good, the Bad, and the Ugly' (among others). `The Blob' proves to me no match for Steve McQueen, star of `Wanted: Dead or Alive'.

    Other famous cowboys featured in 1950s sci-fi movies include Eric Fleming (`Rawhide') in `The Conquest of Space' and `Queen of Outer Space', Michael Landon (`Bonanza') in `I was a Teenaged Werewolf', and Ken Curtis (`Gunsmoke') in `The Killer Shrews'. Sci-fi veteran Richard Carlson never achieved fame as a cowboy star, but he did get to play a cowboy in Ray Harryhausen's faithful 1968 version of the ORIGINAL cowboy-versus-dinosaur idea -- which was first thought up my Willis O'Brien back in the 1930s; `Valley of Gwangi', twenty years before `Beast of Hollow Mountain'!

    Interesting story line, great monster for that time period, I really enjoyed this movie.

    I first saw this movie as part of a group of summer matinees offered for children. Later, I remembered it when it came on TV as part of a Cable TV Monstervision. This movie has some very interesting scenes, it is good family entertainment. I will try to contact the Cable TV Networks to please air this movie so others can enjoy it. IF ANYONE KNOWS WHERE I CAN GET A COPY OF THIS MOVIE, PLEASE E-MAIL ME.

    This is no 'King Kong', but it's still a treat.

    It is said that a mountain surrounded by a swamp is hollow and that a prehistoric monster from 'the dawn of time' comes out during times of drought to stalk the land.

    Alright, so the plot lacks any sense of reality (there would have to be a whole race of dinosaurs for them to survive until the present day). The special effects also leave something to be desired. But look over these faults and you'll find that this film is actually very enjoyable and entertaining. The dinosaur isn't revealed until the last twenty minutes, but when it shows its face there's non-stop action, and for once the dinosaur can move fast and so poses a genuine threat. The dinosaur itself is fairly well-animated and there is a wonderful 'golden age of monster movies' feel about the whole thing.
