MOVIES - April 16, 1987

“Star Wars” trilogy star and show-biz scion Carrie Fisher already has a film deal for her first novel, “Postcards From the Edge,” due out in August by Simon and Schuster. Fisher’s William Morris agent, Irene Webb, arranged a film development deal at MGM for “Postcards”--one that carries a six-figure down payment and would allow Fisher to write the screenplay. The book is about a young actress who veers from self-destructive behavior to wisdom and back again. Fisher’s own experimentation with mind-altering substances and her fight to be free of them have often been publicized.
