"Red Alert" author Peter George collaborated on the 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 novelization of the actual film, rather than a reprint of the original novel, was published by Peter George, based on an early draft in which the narrative is bookended by the account of aliens, who, having arrived at a desolated Earth, try to piece together what has happened. It was reissued in October 2015 by Candy Jar Books, featuring never-before-published material on Strangelove's early career.
