Even "The Bionic Woman" likes some serious sack time. On Friday Lindsay Wagner was at Orbit Studios, the premier photographic rental facility in the Midwest, shooting a print ad for Select Comfort, the Sleep Number Bed. Terri Odland, a studio manager who is a producer for Orbit's owner photographer Bob McNamara, said Wagner was very nice. "I think they were in town doing video commercials and stuff," Odland said. "She was very gracious. We've had some superstars in here who have made many more demands than she."
