It began with her roman a clef, “Postcards From the Edge,” in which Carrie Fisher retold the tale of her troubled, starry life. That bestselling novel begat an Oscar-nommed movie starring Meryl Streep. But when Fisher strayed from her own story with “Surrender the Pink,” “Delusions of Grandma” and “The Best Awful There Is,” Hollywood and book buyers didn’t come calling in the usual droves. Wisely, she went back to basics with a memoir, “Wishful Drinking,” which included the old stories of drugs, Leia, Debbie and Eddie. Since this movie had already been made, Broadway came to the rescue with Fisher’s one-woman show, “Wishful Drinking.” Can’t wait for the tuner version.
