“In Search Of” was a documentary series hosted by actor Leonard Nimoy. The show ran in the 1970’s and it’s subject matter covered the mysterious, the supernatural, the uncanny and the just plain weird. Here is a sample episode that pursued the topic of Bigfoot. I remember watching this program religiously on Sunday evenings and enjoying it immensely. A precursor to the vast amount of supernatural/docudrama series which populate the cable TV landscape today. Worth seeking out.
