ANSLEY, NE—Persistence Of Vision, a screenplay by aspiring screenwriter James Grunau, "isn't quite ready to shop yet," Grunau's 57-year-old mother Doris told her son over breakfast Monday. "I know you worked really hard, Jimmy, but I think this could use another good punch-up," Grunau said of the 115-page draft. "I just don't think anyone will relate to Donna, and the second act feels flat. You need to raise the emotional stakes." Ms. Grunau then offered her son some butterscotch pudding.
