In the intro/theme song for the 1965 TV show Lost in Space the actor who played Dr. Zachary Smith (Jonathan Harris) is listed as a special guest star. How could this be if we look at the meaning of a guest star:

In show business, a guest appearance is the participation of an outsider performer (such as a musician or actor) in an event such as a music record or concert, show, etc., when the performer does not belong to the regular cast, band or other performing group. (Source: Wikipedia)

However, he appeared in a lot of (if not all) episodes so he shouldn't have been called a guest star, but a normal star.

Is there any reason for this? I think he was also shown as a special guest star for all the seasons.

  • Heather Locklear was also billed as a Special Guest Star the entire time she was on Melrose Place, although she was effectively the lead actress.

  • Rule of thumb: "Special guest star" vs. regular cast member is only very loosely related to actual frequency of appearance. It's usually got more to do with negotiations between the actor('s agent) and the producers, the timing of when an actor joined, marketing concerns ("and special guest star [bigname actor]"), etc.

  • On a point of clarification, the facts are these: the tv show comprised a 60 minute pilot plus three regular seasons. Jonathan Harris ("Dr Smith") was not in the 1964 pilot, but was in every episode of the three seasons, made between 1965 and 1968.

At the point where Jonathan Harris joined the show, everyone else had already signed contracts that said where their names would be put on the billing, so he unfortunately would have to be last. As consolation, he negotiated to be listed as a "Special Guest Star" because it was "ridiculous", according to what he said at New Jersey's Chiller Theatre Expo in 2001:

I called a friend of mine who was head of casting at NBC and I asked, "Have you ever given billing, in all of the series that you've done, to somebody for whom it will say, every week, Special Guest Star Jonathan Harris?" He said, "Don't be silly! I wouldn't give billing like that! That's ridiculous billing! It doesn't exist!" And at that time, it did not exist. I said, "THANK YOU! That's all I need to know!"

I called Allen and said, "I solved your billing problem." "Eh? What?," said Mr. Charm. I said, "I will accept last position: Special Guest Star Jonathan Harris." Well, the next 20 minutes you would not have believed! "YOU GODDAMN ACTORS YOU CAN'T ACT ANYWAY! NONE OF YOU ARE WORTH A NICKEL AND I'VE GOTTA PAY ALL YOU BASTARDS!!!" And on and on. [Laughter.] I didn't open my mouth! I just sat there and listened. "YOU CAN'T ACT ANY OF YOU. YOU'RE THE WORST OF ALL, YOU CAN'T ACT AT ALL!!!" On and on. I took a deep breath and said, "OK!" and hung up. Amazing! That was the first time that kind of outvie billing occurred. Now, of course, billing is total madness: "With the Special Appearance of ... With the Appearance of ... With a Cameo Appearance of ... " I started that whole crap!
Never fear, Smith is here!

  • Nicely done. I think the only point I should clarify is that, in the beginning, Irwin had signed all the other actors to 7 year contracts before he would make the original pilot episode. Smith was not in that pilot. So when the show was given the green light to go to series, everyone else already had cast-iron contractual billing agreed. Now Smith had to be added, and he had to be added in last place. But the actor came up with a solution he could live with. An unusual one, and an imaginative one. Bad luck on the Robot, who also got added, but Dick Tufeld got no billing at all!

Jonathan Harris did not join the cast of Lost in Space until after the show was already in production, not being in the pilot. At this point the billing had already been finalized, so through contract negotiations, he was able to be billed as a 'Special Guest Star' for every episode. According to him, starting the entire "Guest Star" billing in television period.

As from the Interview Transcribed here.

I called Allen and said, "I solved your billing problem."

"Eh? What?," said Mr. Charm.

I said, "I will accept last position: Special Guest Star Jonathan Harris."

Or if you care to listen, from the horses mouth. Here is a direct mp3.


Smith wasn't in the show as originally conceived (or in the original un-aired pilot). When the show did go to air with a re-worked pilot (in which he sabotages the ship), it was originally thought that his character would be a short-term villian (per this article on Wikipedia), accounting for his "special guest star" billing. Due to his popularity and flamboyance, he was kept on and the billing continued as it was.

  • Throughout the early first season, it was firmly in Jonathan Harris's mind that the character he was playing had no longevity, because Smith as conceived in the script for Episode 1, The Reluctant Stowaway, was a "heavy" -- a fairly nasty villain. Harris believed there was every chance Smith would be written-out, probably at the conclusion of Episode 6, the end of the mini-series with which season one opened on the hostile planet. So when he agreed his unusual billing, he genuinely had no confidence that he was signing a run-of-the-show contract. He only expected to be in 6 episodes.

  • @Ed999 And when you see his first appearance in the show, he does appear, initially, to be a competent, evil saboteur. It's only as events unfold over the first few episodes that you can see his character evolve to the inept, bumbling fool we all remember him to be.
