Some changes to the show's premise were made between the first 'Six Million Dollar Man' TV movie and the sequel. In the first film, Austin is described in dialogue as being a civilian, but in this film this is changed to him being an Air Force colonel (and dialogue confirms this version of the character was a colonel at the time he walked on the moon). As noted above, Oliver Spencer is replaced by Oscar Goldman (a character from the original Cyborg novels) and a new actor plays Rudy Wells. In addition, the organization Austin works for is now the OSI, not the OSO.
