From 1955 comes one of the most unique films that was later adapted to educational television. "Journey into Prehistory" is a 1955 Czechoslovak science fiction adventure film directed by Karel Zeman. 

William Cayton and Fred Ladd produced a dubbed and partly re-filmed US version of the film that was released in 1960 under the title "Journey to the Beginning of Time".

Karel Zeman was every bit as much of a showman as Walt Disney, Ray Harryhausen and Jim Henson. With much of his work dubbed into other languages and distributed internationally, Karen Zeman was a moviemaker with a world-wide following.

Notice:

I posted the cleaner upload version which is missing the last 20 minutes of the film.

This next version has the missing ending but the quality is not as good, in my opinion:

Here is something I never imagined I would see. This is Karel Zeman's original 1955 film in Czech.
