The OSO acronym appeared in the first TV movie, as well. Steve's boss in that outing was a real jerk named Oliver Spencer, played by the great (and sadly late) Darren McGavin. Spencer treated Steve as government property and wasn't very sympathetic at all to his depression over becoming half-machine (a neat subplot dropped after season one). Interestingly, McGavin gave Spencer a cane and a limp, which supplied a neat subtext to the whole thing (ie: maybe he's jealous of Steve's prostheses?). At the end of the film, he asks Dr Wells whether they could just put Steve to sleep and store him somewhere until the next assignment.
By the time of the second movie, if memory serves, Oscar Goldman was in place and the name was changed to OSI. (In the novel, I think Goldman was just a middle-management type and not the director).
Blast it, why isn't this show on DVD?!?!?!
But it is on DVD, Nightwing. I have rented the whole first season on DVD from my local store. The set included "The Six Million Dollar Man" ("The Moon and the Desert" pilot film), both subsequent TV movies (which I don't like), and all of the first season episodes from "Population: Zero" onwards.
Yes, I know the pilot film well as I have watched it recently again. I think one of my earliest memories is sitting down with my Dad to watch the new "Six Million Dollar Man" TV show. Those were the days. That regular opening sequence still sends a thrill down my spine every time I see it. I thought Steve was pretty darn cool in those days! I think Lee Majors did a top job and the success of the show is thanks mainly to him. I also think his charisma and good looks held the whole thing together long after it descended into outright nonsense.
