Yes, just like Cary Grant never said "Judy, Judy, Judy", Jimmy Cagney never said "you dirty rat", Sherlock Holmes never said "Elementary, My Dear Watson" and Humphrey Bogart didnt say "play it again, Sam" in 'Casablanca'.
Basically that is all I have received is that Star Trek never had headshots at the beginning, which doesnt explain where Pigs In Space might have gotten idea for the parody.
One responder even opted to analyze that the headshots of the pigs represented their egos, which was about the furthest from what I was after.
So the original Star trek show, the cartoon neither had these headshots.
The only other parodies that I can think of would be either Saturday Night Live's spoof with John Belushi or Secret Lives of Waldo Kitty, which had a Star trek takeoff.
Not likely either of these will be viewed anytime soon, but is this what occurred somehow? The parodies of Star Trek began having headshots of the figures slowly moving toward the camera and that became attached to star trek, which we (or I) now know never took place?
Space: 1999 didn't have headshots at the beginning, but rather waist-up shots of the two stars, Martin Landau and Barbara Bain. Considering that The Muppet Show and Space: 1999 were both released by ITC, and that the former followed the latter by only a few years, I think it's a likely candidate.
Lost In Space had headshots, but if you recall Pigs In Space, the headshots of Linc Hogthrob, Strangepork and Miss Piggy would all start far off, then slowly inch forward as they were described.
Now the description by the narrator, I never heard, what I always thought was the case was that the original Star Trek had the same slow moving headshot and we heard the theme.
I think I posted this query after I got hold of two episodes from the cartoon and was surprised to see that it too didn't have the headshots.
Or I should say the MOVING headshots, moving in toward the camera.
Lost In Space doesnt have this, and it has been such a long time since I have seen Space:1999 but I'm fairly certain it didn't have those moving inward headshots either.
AND I never saw Lost In Space when I was little, nor Space:1999.
I would see Space:1999 about the latter part of the 1970s, after the Muppet Show and boy, I am late into Lost In Space.
Just saw that show in about the past 8 years (I'm 41).
