A most interesting and weakly executed Sci-Fi diversion, where we have a somewhat unbalanced scientist proposing a theory that brain size is indicative of intelligence. A theory laughed at by fellow scientists in this film, but now recognized as accurate.
Of course, in the film, the scientist promotes as fact that brain size of the neanderthal is perhaps even larger than modern man, when it was not. That's the flaw here, but still we get to see him revert himself back to a neanderthal with violent tendencies, probably also pretty far-fetched. I'd expect a neanderthal in today's world to be more bewildered and frightened than overtly violent for no reason.
Also of notable fun is the "reversion" of house cats to sabre-tooth tigers. Pretty unlikely as they're not really evolutionarily that closely related in any line. But still fun and in one case, ironically deadly.
This is mild low-budget 1950s science fiction, short enough to not be tedious, although the excessively prose dialog is annoying. It's almost like writing in a period stage-drama style of the 1900s, and applying it to a 50s B-movie.
While merely okay, this film could have been so much better in the hands of Jack Arnold and the sci-fi effects wizards at 1950s Universal-International. Oh, wait, I just remembered they did it as Monster on the Campus.
