Beyond and Back (1978)
This Sunn Classic Pictures documentary made the rounds of cinemas, drive-ins, and early cable television for some time before fading from wide viewings.
Sunn Classic Pictures was an independent production company based out of Utah; where this was filmed. They put out a number of movies, including In Search of Historic Jesus (1979), In Search of Noah's Ark (1976), The Lincoln Conspiracy (1977), The Bermuda Triangle (1979), and Hangar 18 (1980).
James L. Conway directed this and some earlier titles for Sunn before trying R-rated horror with 1981's The Boogens, then moving to an ongoing and successful career in television work. In spite of Sunn Classics heavy Christian editorial stance; this was shot by cinematographer Henning Schellerup, who had also filmed pornography in the late '60s/early '70s and continued to work on many exploitation/horror films.
