For many, “The Witches of Eastwick” brings up images of the 1987 film starring Jack Nicholson and Cher. It was also eventually adapted for theater and TV. Originally, however, it was a 1984 novel written by multi-Pulitzer Prize-winning author John Updike, who spent many years living in Massachusetts. Both the novel and film were set in a fictional Rhode Island town, focused on three divorcees who discover they have magical powers. The story’s New England connection got deeper during the making of the film, which was shot in Ipswitch, Marblehead, Cohasset and Scituate, Mass.
