This is the trailer for The Beatniks, a 1960 exploitation movie that was apparently filmed on a budget about equal to what I spent on Snickers bars that year. I never made it through the entire picture — if you want to try, it's available on DVD — but it has that campy, Jack Webb "the kids today are bums" message that I guess was commercial with some segment of the population back before "the kids today" were the primary audience.
You may notice that the voiceover on this trailer is by the legendary Paul Frees. Paul did some narration for schlocky projects but this may well be the schlockiest. How did they land him for the job? Well, it may have something to do with the fact that this movie was directed and co-written by Paul Frees…
