NAPLES, Fla. -- For his role as a nationally renowned cardiologist and researcher, actor Tom Riska read his 100-page script for roughly three hours, stumbling on a few medical words. After boning up during a lunch break, Riska, 60, was confident with his script's medical jargon -- and his part as Dr. Rajendra H. Mehta went off without a hitch.
This wasn't a medical TV show or soap opera. Riska was "testifying" as an expert witness in court, where a surgeon and his physician assistant were on trial in a medical malpractice case.
