If you're a 50's "B" movie fan like I am, this is a gem. I saw this film back when i was a kid, something like 1962 or so, and it hasn't been on T.V. in years. I have a VHS copy of it but would love to find it on DVD sometime in the future. When a caveman throws a hatchet and it hits a cop square in the face, it leaves an impression on you when you're 10 years old. Of course, by today's standards, it looks kinda hokey, but you have to keep in mind that movies like this one "pioneered" this type of movie. I wouldn't trade a 50's "B" flick for all the new garbage in the world. Like, what could measure up to movies such as the transparency of "The Amazing Colossal Man" and "War Of The Colossal Beast?" Ah yes, those were the days. Back when sci-fi movies didn't have to be VULGAR to be entertaining. The special effects didn't even have to be good - we STILL loved it! I sure wish the Time Tunnel was a reality - I'd go back there in a new york second!
