Speaking of books as movies,
Ira Levin just died author of Rosemary's Baby, The Boys From Brazil as well as The Stepford Wives. All 3 made into good, if not great films (as much as I love Frank Oz, I thought the newer campier Stepford Wives was lame, just as the earlier one was cheesy, but truer to the original book) Rosemary's Baby, terrific film! I need to read the book and it's been decades since I read Stepford Wives.
