James Franciscus plays Tuck, an amiable hustler who comes back into the life of T.J. (lovely Gila Golan). T.J. is one of the participants in a Wild West show that is not doing so well at the moment. However, one of their people, Carlos (Gustavo Rojo) has ventured into a Mexican location known as the "Forbidden Valley" and come back with a prize: an adorable "Eohippus", or miniature prehistoric horse. Circumstances lead Tuck and others to head into the valley, where they encounter other ancient animals, such as a Styracosaurus and a very aggressive Allosaurus.

In the well loved tradition of "King Kong", T.J. and her friends, including Champ (Richard Carlson), get the bright idea to introduce the Allosaurus - who gets christened Gwangi - to their show. Havoc predictably ensues.

There may be viewers who will grow impatient with the pacing at first. "The Valley of Gwangi" runs longer than previous Ray Harryhausen - Charles H. Schneer productions at 96 minutes, and it's not until the movies' second half that we get to see any dinosaurs. But the little Eohippus is sure to charm people, not just children, and the story is very engaging.

It helps that the actors are so sincere. The handsome Franciscus is good in the starring role, with fine support from Ms. Golan and Mr. Carlson. Young Curtis Arden is appealing in the role of Lope the child, who had to fend for himself from an early age and who is clearly eager to make a buck. Freda Jackson is amusing in the somewhat annoying, clichéd role of the wise old doomsayer who rants about the consequences of individuals going into the valley and bringing back "evil" specimens.

As expected, Harryhausen's special effects are excellent. They're especially impressive in the movies' major set piece, when Tuck, Champ and others work overtime to try to lasso Gwangi. And once the action kicks into gear in this thing, a real fever pitch is reached and then maintained until the absolute end, with an exciting rampage.

Mostly lighthearted entertainment, but G ratings weren't always what they are now: a few people do fall victim to the jaws and teeth of Gwangi.

Very well directed by Jim O'Connolly ("Crooks and Coronets", "Tower of Evil").

Seven out of 10.

Say, have you noticed this? In practically every dinosaur movie I've ever seen, there's always a point where a Tyrannosaurus-like dino, in this case an allosaurus, matches up against a Triceratops-like animal. In this picture it was a Styracosaurus. It's probably because they were the largest of their kind and seemed like natural enemies, although I don't even know if they lived during the same paleontological age. Is that even a word?

Well this flick is entertaining enough on a number of levels. For one, I don't think I've seen dinosaurs as colorful as this before. Usually they're a dark, grayish color but someone, maybe Harryhausen himself, felt they should be various shades of purple and blue. Or was that a function of the Technicolor format? If you noticed Professor Bromley (Laurence Naismith) running around out in the desert, his face and hands were red as a lobster; I've never seen a sunburn that bright.

While watching, I was reminded of the 1949 movie "Mighty Joe Young" when the Mexican cowboys brought out their lassos and tried to hogtie the allosaurus. I'm sitting there thinking, what would possess someone to believe they could actually do that with a real live dinosaur? Sure it looks cool, but what self respecting dinosaur wouldn't just bite through the ropes and knock the pesky cowboys off of him, just like Gwangi did here.

Say, here's another thought. I've probably seen and reviewed close to a thousand Westerns by now, and you might loosely call this a Western, but I've never seen a horse dive into an oversized pool before. So there's another reason to catch this flick. Seeing Gina Golan all wet is a bonus.

So all in all, this is a fun movie if you're up for it. James Franciscus and Ms. Golan make for an attractive on screen couple, and the dynamation styled monsters looked and moved fairly realistically given the limitations of the technology back then. And who wouldn't love to see some dinosaurs at a Wild West Show?

Ray Harryhausen has a unique place in the history of film and it's not the quality of his work. A lot of players are box office names, a few director/producers like Cecil B. DeMille, Alfred Hitchcock, Frank Capra, and Walt Disney most of all bring people in with having their names on a film. But Ray Harryhausen is the only one in his profession as a special effects man who brings folks to the theater. That's the best tribute of all for him.

Late in the 19th century Gita Golan owner of a small wild west show is playing Mexico and she's got a unique attraction as she has found a small horse, an ancient eohippus which has come out of a valley said to be cursed and inhabited by fierce creatures called the Gwangi. An old flame who works for Buffalo Bill, James Franciscus and some of his wild west show cowboys show up to track down the little horse after some local gypsies under the direction of Freda Jackson set it free.

But what they run into is an ancient tyrannosaurus which is called a Gwangi by the locals. It's like when Carl Dedham spotted King Kong, got to get this guy back to civilization and make a bundle off him.

The plot is outrageous with some great overacting by Freda Jackson as the old gypsy crone and Laurence Naismith as a palaeontologist all in the spirit of fun. I love it when Franciscus and the cowboys discover that the reason their bullets are having no affect on the big guy is they're using blanks from the show. Does it deter them, it does not they set about to lariat T-Rex and play an interesting an deadly game of tag.

When they do capture him and later destroy him, it's with a lot of luck and some natural forces in nature.

Dopey plot, but that's part of the fun. And the work of Ray Harryhausen is the reason to see the film and in that you won't be disappointed.
