Wheeler (Frank Gerstle), a tourist-hunter in the California High Sierras, is not believed by the patrons of Webb's Cafe when he claims to have run across a live tiger with tusks. Among the scoffers is game-warden George Oakes -- until he is driving home later that night and the critter hops on the hood of his car.

The general idea of this film is pretty standard -- you have a mad scientist who wants to turn people into Neanderthals and cats into saber-toothed tigers. There are plenty of scientific arguments that can be made against this being possible, but let us just ignore that...

He gets especially upset when his theories are presented to the local natural history society and they scoff at him. Interestingly, he includes Piltdown Man as part of the evolutionary chain of man -- a fossil that was determined to be a hoax in November 1953, around the same time as this film came out...

What could be considered really sad about this film is that it comes from director E. A. Dupont, who used to be somebody. Once upon a time, he was a big name in the world of German silent cinema, writing and directing "Variete" starring Emil Jannings and with Karl Freund operating the camera. A classic film. And now, at this point, he is directing cheesy science fiction with cheesy makeup and no real directorial flair. This is your average science fiction film of the 1950s, with almost no notable names (besides Dupont). He could have done better...

The one possibly notable name is Beverly Garland, who played the waitress. Although not A-list, she did go on to appear in multiple Roger Corman films and continued acting up through the 2000s on shows such as "7th Heaven". Some could say Robert Shayne was notable, but aside from bit parts in "North By Northwest" and "Invaders From Mars" he hardly left his mark.

Although perhaps talking this movie down, I am not saying you should avoid this film, but just be prepared for the average 1950s flick, probably not something you will tell your friends about. For those who really must see it, Scream Factory has released a nice blu-ray of the film, with a fairly decent transfer (though no special features).

A haughty Professor becomes intent on proving that mankind's gradual evolution did not necessarily affect his quotient of intelligence. Despite the distinguished directorial credit, this is a thoroughly routine horror programmer of the 'mad scientist' variety, with more than its fair share of unintended hilarity amid the general tackiness. In fact, I would go so far as to say that, as played by Robert Shayne, the doctor here is the rudest in film history and watching him let rip with insults at his staid, disapproving colleagues was a hoot! Typically for this sort of fare, the all-important serum is first tested on animals or 'lesser' humans – in this case, a perennially terrified domestic cat is turned into a saber-toothed tiger and a mute servant girl into a bushy-eyebrowed ape woman (albeit, apparently, just long enough for her to sit for some photographic evidence of the veracity of his claims) – before applying it to himself. The proverbial redneck hostility to a marauding tiger preying on their livestock and later a simian kidnapper of women is present and accounted for; what is more surprising is that the middle-aged professor has a good-looking and much younger fiancée who still relishes hopes of dragging him from his laboratory off to a church altar and, naturally, once the young urban expert hero comes along, he falls for the charms of the professor's clueless daughter. The TNT-culled print I watched left an awful lot to desire so, in spite of my reservations, I acquired a superior copy of the film the minute it was over!

A rip off of "Dr. Jekyll and Mr. Hyde", this takes a lot of patience to tolerate Household cats become giant beasts and a moody scientist turns into a prehistoric man, growing more facial hair than the wolf-man. His friends and family suspect that something is up but let him be. When people start being attacked he feigns sympathy. Of course, where there is caveman, there must be cave-woman and that is where the film dissolve s into absolute silliness. Shots of big jungle cats passing as prehistoric cats fools nobody. As the truth of what is going on is revealed, the film moves into melodramatic drivel that seemed more appropriate for the decade before when Lon Chaney Jr. was making films like this by the dozen.
