Brief Description  The Slime People (released in 1963, filmed in 1962) is an ultra-low-budget black-and-white science fiction monster movie directed by and starring Robert Hutton. The film is notorious for its heavy use of fog machines to mask its meager budget, resulting in parts of the action being completely obscured.

Plot:
The story begins in media res. A race of subterranean reptile-men, dubbed "Slime People", are driven out of their underground homes by nuclear testing. They invade Los Angeles, using a strange machine to construct an impenetrable "solidified fog" dome over the city. This wall traps the remaining citizens and drops the local temperature to mimic their native underground habitat. Tom Gregory (Robert Hutton), a sports pilot, flies through a dense fog bank and lands at a completely deserted Los Angeles airport. He crosses paths with Professor Galbraith (Robert Burton) and his two daughters, Bonnie and Lisa. They explain that the Slime People attacked, the U.S. Army lost the battle, and the city was evacuated. Along the way, they pick up a Marine private named Cal (William Boyce) and a cynical, spear-wielding beachcomber named Norman Tolliver (Les Tremayne).

The group holes up inside an abandoned KTTV television studio. They use the equipment to watch old newsreels detailing the invasion. Professor Galbraith realizes that the Slime People are highly susceptible to sodium chloride (common table salt). Recalling that Tom saw a monster dissolve when exposed to the ocean, the professor engineers a salt-solution machine. The survivors successfully deploy the salt spray, causing the dome to dissipate and destroying the monsters just as military forces arrive to rescue them. The film was produced for roughly $80,000. The film could only afford eight monster suits (some sources say only three), which cost $600 each. To create the illusion of an army, the same stuntmen were constantly re-filmed running across the camera from different angles.
