Mason made for TV movies. At that same time, Raymond Burr and his associates were busily filming their episodes for Perry Mason. In and around the Embassy Suites Hotel at that time, it was not unusual to see several semi-trailers parked street-side in support of the production at various office or exterior locations in and around downtown Denver. Both series were produced by the Hargrove, Silverman team with Viacom. Therefore, the business decision to combine both productions at the same location was evident. While the Perry Mason series was often filmed in a special courtroom constructed for the production within The Denver City and County Building, Diagnosis: Murder was temporarily set at the then recently closed St. Luke’s Hospital on 19th Street just east of downtown. When Raymond Burr became terminally ill later that summer, he no longer was seen at the hotel after having filmed his last episode, The Case of the Killer Kiss. (1993) In fact, upon his demise, Paul Sorvino was seen entering the hotel building to begin filming what was to be the last Perry Mason episode ever filmed in Denver, – A Perry Mason Mystery: The Case of the Wicked Wives (1993). Upon completion of that filming, Viacom and the entire production company left Denver in late September, early October 1993, including that of Diagnosis: Murder. Thus, only the Diagnosis: Murder episodes filmed from mid-July through September 1993 were shot in Denver, after which production shifted permanently to Los Angeles.
