Remember that when this movie came out that computers were starting to look like Sonny, especially the Macs, see through plastic and so on.  I guess now he would look like a stainless steel sculpture or something like that, and next?  Who knows.

From what I understand, the movie was originally called HardWired or something like that and then Fox realized that they had the rights to the book so they sort of merged them together.  The book is actually a set of stories about Susan Calvin and there's an illustrated screenplay that was released in paperback by Harlan Ellison that puts them all together in a style like Citizen Kane.
