(FORTUNE Magazine) – Gay activists have made ((known)) their displeasure over director Paul Verhoeven's thriller Basic Instinct . . . since the film went into production last year. Now, a group of San Francisco protesters ((has)) taken a step that they hope will stop people from going to see it once it's released. The group has named themselves ''(------) Did It,'' after a bisexual woman character who becomes a serial murder suspect. Leaders of the group hope that in revealing the film's ending, their organization will . . . discourage potential moviegoers . . . The thriller starring Michael Douglas and Sharon Stone opens March 20. (The Times has a practice of not revealing movie endings . . . Therefore, Film Clips will not reveal the character's name.) -- From an item in the Film Clips column in the Los Angeles Times.
