A horror movie based on Wade Davis’ non-fiction book about the case of a ‘zombie’ in Haiti, “The Serpent and the Rainbow” was directed by Wes Craven (best known for the “Nightmare on Elm Street” film series). It starred Bill Pullman, leading a cast of mostly unknowns.
It was a very loose adaptation of the book, with considerable liberties taken with both Davis’ account and the facts, but a lot more horror added. It grossed a respectable US $19 million, well over double its budget.
