The Witches, starring Octavia Spencer and Anne Hathaway, is streaming on HBO Max. It's an adaptation of the 1983 Roald Dahl book about a kid and his grandmother who get caught up in the dastardly plans of a group of child-hating witches at a seaside hotel. The book's action takes place in Britain, but director and co-writer Robert Zemekis has changed the setting to 1960s Alabama, and made the kid and his grandmother Black.
