Glenn Close has developed a fatal attraction for cable. The Oscar-nominated actress is joining the cast of FX's The Shield as the new captain of the Farmington precinct. Close will appear in all 13 episodes of the show's fourth season, which kicks off in March. "Glenn is flat-out, hands-down one of the very best actresses on the planet," raves series creator Shawn Ryan. "We think this is an extremely unique, dynamic character that shakes our Shield world upside down over the course of the entire season." But will she have a bigger trailer than Michael Chiklis? That's the big question.
