Sturgeon suffered from long bouts of writer's block, but was somehow able to produce this story in 9 days. It is one of his most famous stories, and was his most financially successful during the first decade of his career.The story inspired a 1974 TV-movie and a Marvel Comics adaptation by Gerry Conway and Richard Ayers in Worlds Unknown #6 (April 1974).
