Trivia

The "electronically recorded message from the Zeta Galaxy Law Enforcement Bureau" that the Jupiter 2 receives at the beginning of the episode is actually the phrase "Space capsule Alpha seven-eight-four has been pulled out" (that the Alien Leader says moments later in the show) spoken backwards.

Silver Alien Invader Show That Was Shown Out Of Production Order
1 June 2007 | by StuOzSee all my reviews

Episode eleven in screening order but episode four in production order (after Condemned Of Space, Hunter's Moon and Space Primevals). In production order, this was the first of several year three shows with silver skinned alien invaders. These invaders, one played by Ron Gans, are after a deadly female robot...who the Robinson robot falls in love with.

This is a half silly story which many fans think was made mid-season when things slowly started getting less "serious" but in reality it was made very close to the start of year three. It is a bit of a surprise that Irwin Allen would produce something this camp at the start of a season that was attempting to be more "serious" than the previous season. Who knows what happened?

Despite a sometimes silly story, this is not done in the same tone as year two at all. Action, ray gun battles at the campsite, explosions, Jupiter 2 space travel in the teaser, a death threat in the teaser, this was not year two at all. Interestly, when alien Ron Gans attempts to be serious with John and Don, it is a little hard to take him too seriously. Blame the writer not Gans.

I refuse to comment too much about the robot love story. I am sure some other user will comment on that side of things. Let me just say that pushing this hour back to episode eleven was a good thing. Deadliest Of The Species is not as bad as many would think but it is just not good enough to be shown at the start when all effort was being made to improve Lost In Space.
