"Red Alert" author George collaborated on the "Dr. Strangelove" screenplay with Kubrick and satirist Terry Southern. "Red Alert" was more solemn than its film version and it did not include the character Dr. Strangelove, though the main plot and technical elements were quite similar. A novelisation of the actual film, rather than a reprint of the original novel, was published by George, based on an early draft in which aliens try to understand what happened after arriving at a wrecked Earth.
