Space Adventure
3 December 2016 | by See all my reviews

The Jupiter 2 is back in space, and Smith has a contstantly growing plant in his cabin.

The man-sized plants in this episode had previously been seen in a third season Voyage to the Bottom of the Sea titled: The Plant Man.

I like this hour a lot as it is loaded with space action on the Jupiter 2. Guy Williams seems to be having a ball as he is all over the place in this adventure.

There is a brief moment where Judy and Penny talk about going home that lingers in the memory.

Granted, there is the odd child-ish moment I could have done without, but The Flaming Planet moves along rather nicely.

Trivia note: Irwin Allen's Land Of The Giants was filming at this point and I have heard reports that the Jupiter 2 sets had to be moved around to make way for the "Giant" sets. At one point in The Flaming Planet John/Don appear from some top deck corner of the Jupiter 2 not normally seen (usually they would just climb up from the lower deck), and I suspect this happened because the lower deck set (which was on a separate stage to the upper deck set) was moved around.
