Psychologically speaking, the Navy was perceived as being above board as compared to the other military services. The Vietnam War was ramping up by the time that the film was released so this movie had no social "stain" attached to the Navy.
The Navy vs. the Night Monsters was released in 1966. I remember seeing this film at the base theater at Dyess AFB, Tx either in 1966 or 1967. It was shown as a Saturday matinee and the theater was filled to the brim with kids...it was a raucous group high on Hersey bars and soda...no diet sodas back then...pure sugar.
Here is the plot summary from Wikipedia:
A group of scientists discover biologic specimens dating back to the first Ice Age. A plane carrying the prehistoric trees and plants is scheduled to touch down for refuelling at a naval weather station base on "Gow Island" before continuing on to mainland for further research. Along the way seven of the eight passengers on board mysteriously disappear, and the pilot crash lands the plane on Gow. As the only apparent survivor, the pilot is found in a state of shock, leaving the members of the Naval base to determine what happened.Unloading the trees from the plane, the local scientist Dr. Beecham recommends planting them in local soil to ensure they survive. It is later discovered that the trees are actually acid-secreting monsters that kill, and it is up to the locals to figure out how to stop them.
The cost for the movie ticket, a dime. Candy bars were a nickle, the Coke was a dime. To some movie goers today, this would truly be a paranormal phenomena. CIA conspiracy?...hardly...perhaps a subliminal message that environmentalist wanted to portray... a stretch at most.
