The show was sued by Humana because of similarities between the company and "Ecumena", the company that took over St. Eligius in the show. The show eventually dropped the name and issued a disclaimer on each episode.
Dr. Mark Craig:
Throughout the series, Dr. Daniel Auschlander suffers from late-stage Liver Cancer and yet he is seen repeatedly as drinking "very good" Scotch after hours with his staff in his office. Alcohol consumption only aggravates Liver Cancer and hastens death.
In the final season, St. Eligius has been bought by Ecumena. In several episodes of the final season, the following message appears during the end credits: "ECUMENA is a fictional company that does not represent any actual company or corporation."
The versions shown on Bravo cable network in the United States have many of the songs used throughout the series replaced with generic stock music, probably due to licensing issues.
