Gas-s-s-s (on-screen title: Gas! -Or- It Became Necessary to Destroy the World in Order to Save It.) is a 1970 post-apocalyptic black comedy film produced and released by American International Pictures. It was producer Roger Corman's final film for AIP, after a long association. He was unhappy because AIP made several cuts to the film without his approval, including the removal of the final shot in which God comments on the action — a shot Corman regarded as one of the greatest he had made in his life. The movie is a post-apocalyptic dark comedy, about survivors of an accidental military gas leak involving an experimental agent that kills everyone on Earth over the age of 25 (a cartoon title sequence shows a John Wayne-esque Army General announcing — and denouncing — the "accident"; the story picks up as the last of the victims are dying with social commentary on Medicare and Medicaid). The subtitle alludes to the 1968 quote "it became necessary to destroy the town to save it" attributed to a U.S. Army officer after the Battle of Bến Tre in Vietnam. The lead characters, Coel and Cilla, are played by Robert Corff and Elaine Giftos, and the cast features Ben Vereen, Cindy Williams, Bud Cort and Talia Shire (credited as "Tally Coppola") in early roles. Country Joe McDonald makes an appearance, as spokesman "AM Radio". Plot In Dallas, at Southern Methodist University, news comes in about a gas which has escaped from a military facility. It starts killing everyone over 25. Hippie Coel meets and falls in love with Cilla. They discover a Gestapo-like police force will be running Dallas and flee into the country. Their car is stolen by some cowboys. They then meet music fan Marissa, her boyfriend Carlos, Hooper and his girlfriend Coralee. Marissa leaves Carlos, who finds a new girlfriend. The group meet Edgar Allan Poe, who throughout the film drives around on a motorbike with Lenore on the back and a raven on his shoulder, commenting on the action like a Greek chorus. They then have an encounter with some golf-playing bikers, after which they attend a dance and concert where AM Radio is performing and passing on messages from God. Coel sleeps with Zoe, but Cilla is not jealous. Coel, Cilla and their friends arrive at a peaceful commune where it seems mankind can start fresh. Then, a football team attacks
