Before watching this on YouTube, I saw a video of Hotlegs' single "Neanderthal Man" which had some members of a later group called 10cc and also some scantily clad young women dancing. This horror film is pretty talky and the makeup to turn someone into the title character is pretty dreary to the modern viewer but if you're familiar with the way transformation was done in these old movies, it's quite a hoot to watch as is the way a normal tiger is suddenly made to look huge and have saber teeth in one hilarious insert! There's also some pretty women like frequent B-movie starlet Beverly Garland who looks quite gorgeous here, I must say! Overall, this was both a little cheezy and dramatically entertaining. Next, I'll watch a more modern take on caveman-in-present-time movie called Iceman...
