Something Wicked This Way Comes is a 1983 American horror fantasy film directed by Jack Clayton and produced by Walt Disney Productions from a screenplay written by Ray Bradbury, based on his novel of the same name.
 The novel's title was taken directly from a line in Act IV of William Shakespeare's "Macbeth": "By the pricking of my thumbs / Something wicked this way comes."
 The film stars Jason Robards, Jonathan Pryce, Diane Ladd, and Pam Grier.
 It was shot in Vermont and at the Walt Disney Studios in Burbank, California.
 The film had a troubled production – Clayton fell out with Bradbury over an uncredited script rewrite, and after test screenings of the director's cut failed to meet the studio's expectations, Disney sidelined Clayton, fired the original editor, and scrapped the original score, spending some $5 million and many months re-shooting, re-editing and re-scoring the film, before its eventual release.
