Josef Beyvl (?) film clip, origin unknown

I was searching on Uloz.to about a few minutes ago, trying to find anything that might be lost before the site "shuts down", and I came across a 5 minute 23 second clip of a 1960-1970 film (presumably) featuring Josef Beyvl, a Czech actor. I can only really assume it's Beyvl from the original file name.

Here's the video. All help is greatly appreciated.
