Chad Everett, who starred in the 1970s TV drama "Medical Center," has died. He was 75. Everett's daughter told the Associated Press that he died Tuesday at his home in Los Angeles after a year-and-a-half-long battle with lung cancer. Perhaps best known for his role as surgeon Dr. Joe Gannon, the actor was twice nominated for a Golden Globe for his perfomances on "Medical Center." The series ran seven seasons and, at the time, tied with "Marcus Welby, M.D." for longest-running medical drama.
