LOS ANGELES (AP) ? Carrie Fisher, beloved by legions of fans for nearly 40 years since she first walked the corridors of a "Star Wars" spacecraft as Princess Leia Organa, is being treated in an intensive care unit after a serious medical emergency on a flight, according to her brother. Todd Fisher told The Associated Press on Friday night that his sister was receiving excellent care, but said that he could not classify her condition. In a subsequent interview he said many details about her condition or what caused the medical emergency are unknown, and much of what had been reported was speculation.
