"Law & Order" star Angie Harmon is on her first hiatus from the hit show that put her in the spotlight, so she's doing what every other series star does these days--looking for the best movie role she can find. That means lots of meetings, like the hush-hush one that made her an hour late for this photo shoot. Here at the new retro-themed Avalon Hotel in Beverly Hills, Harmon leaves behind the tough D.A. demeanor of her "Law & Order" alter ego, Abbie Carmichael, and playacts her own drama--the TV star in search of the perfect big-screen part.
