In Roger “Corman’s Gas-s-s-s Or- It Became Necessary to Destroy the World in Order to Save It” a gas is let loose upon the world that kills anyone over 25 years old. The gas of the title is a chemical weapon developed for the US Army at a top-secret research station in the wilds of Alaska. As we are told in a pre-credits cartoon in exactly the same style as that which opens Creature from the Haunted Sea, the deadly vapor leaks out of its containment tanks, and quickly spreads to envelop the entire world. Resulting in their almost immediate demise from premature decrepitude.
Roger William Corman (born April 5, 1926), sometimes nicknamed “King of the Bs” for his output of B-movies (though he himself rejects this as inaccurate), is an Academy Award-winning American producer and director of low-budget movies, some of which have an established critical reputation: his cycle of films derived from the tales of Edgar Allan Poe for example. Corman is also a sometime actor, taking minor roles in such films as The Silence of the Lambs, The Godfather Part II, Apollo 13 and Philadelphia.
Corman has apprenticed many now-famous directors, stressing the importance of budgeting and resourcefulness; Corman once joked he could make a film about the fall of the Roman Empire with two extras and a sagebrush. One of the most expensive films he produced was Battle Beyond the Stars. —Wikipedia
