Something Wicked This Way Comes has served as a direct influence on several fantasy and horror authors, including Neil Gaiman and Stephen King. Gaiman paid tribute to Bradbury's influence on him and many of his peers in a 2012 The Guardian article following Bradbury's death. Gaiman's novel American Gods can be read as a tribute to and attempt to surpass many of the "dark carnival" themes in Bradbury's work. The motif of ordinary people up against sinister, supernatural forces appears in many of King's works, including It and Dreamcatcher. King also discusses this novel at length in his non-fiction book Danse Macabre.
The book also influenced R.L. Stine, who said, "Ray Bradbury is one of my favorite authors. I always tell people that the scariest book I ever read was one of his books—Something Wicked This Way Comes."
