The Space Trader


A sudden storm destroys the Robinson's food supply, artificially created by an unscrupulous space trader with an ulterior motive. He thereafter makes himself known and uses food to lure them into trading, but Prof. Robinson stands fast. Stuck with limited rations (practically nothing more than a few protein pills and a swig of water), only Dr. Smith among the Robinson party grumbles. The trader soon has Smith doing business, at first trading the robot for food, then for Smith himself to trade the robot back. By verbal agreement, the trader intimates he wouldn't collect Smith for another 200 years, but verbal indications aren't binding, and under the fine print of their signed contract, the trader exercises a clause whereby he can collect - now! (his intent all along). Written by statmanjeff

Did You Know?


The Space Trader's space ship is also Alonzo P. Tucker's space ship from Lost in Space: The Sky Pirate (1966). See more »


The Space Trader launches the first storm (in the opening scenes) and everyone is forced to go inside the spaceship. As the robot is going up the ramp, its forward progress slows and then it lunges forward. As it does, the robot's front treads lift off the ramp and its weight is way behind its base. Clearly the robot fell backwards while filming this scene. Played back slowly, you can see Angela Cartwright reach out to grab the robot as it starts to fall. See more »


The Space Trader: Only the robot. That's the only thing I'm... REALLY interested in.
Dr. Zachary Smith: Ah.
The Space Trader: I-if you COULD manage to trade that machine, I'd give you all the food you could possibly eat.

Smith makes a deal with a Space Trader.

I can't really say this hour is a favourite of mine. I don't dis-like it but I don't like it. Perhaps the problem is that it seems like one of those later season two episodes but done in season one. You know what I mean...another oddball alien hanging around a campsite somewhere and Smith making yet another deal with him. The guest stars are vital to LIS and the guy playing the Trader plays the role in a rather boring way.

Also, I felt sad for the Robot being put in this situation.

But this is LIS, one of the greatest TV shows ever made, so it is still worth a look.
