I first saw this film on TV in 1978. I only watched the middle story, however before we switched channels to watch "And Now the Screaming Starts" instead. I was only 7 years old, but the story and images stuck with me all these years. I caught a glimpse of the second story again (the hole in the earth tale) in 1980 in L.A.'s Greyhound Bus Terminal on a pay-per-view TV in the waiting areas. Ever since 1997 nobody on the many horror movie Internet forums could identify this film for me! Finally in 2004 I went to the microfilms at the local library to look up that date in 1980 in the TV listings and that is where the title Encounter With the Unknown came be...well, known (or re-known to me). Not soon after, I won the one-sheet poster on Ebay. On March 30th, 2007, I finally scored A DVD R of this (in great condition) from Retroflicks.com. The film - in all its grainy filmstock, unprofessional acting, Afterschool Special soundtrack music glory...all make for ONE CREEPY VIEWING!!!! Films that are too slick (the ones made today) lack the punch these older films have. In fact, during the first tale, I was afraid to watch this film alone in my apartment. So I watched TVland reruns until I had to wait until my roommate came home before I resumed. As a veteran of watching a darn-near lifetime of horror movies, that's saying a lot! What can be considered production "short-comings" to mainstream movie viewers actually WORKS in this films favor! I bought the whole experience and I, indeed, refuse to watch this one alone. The documentary feel is a hoot to watch. In fact, if this film was digitally cleaned and remastered it might lose some of its effect. Still, I'm glad I'm reunited with an old favorite that has lost none of its appeal all these years. It's exactly as I remembered it.
