I strongly believe that big building around the Jupiter 2 when it lands are the Fox Studios (20th Century) sound stages.
It's funny seeing a very young Robert Pine, years before he was on the T.V. show C.H.I.P.S. It's also nice seeing outside scenes with nature lighting instead of controlled lighting scenes done within the confines of interior sound stages
Reasons to note this episode would be to give Will a little crush in farmgirl Stacy who tries to help him and Robert Pine as a downhome country boy who ends up briefly paired with Judy Robinson.
Clunky moments would be Maureen contemplating how an old Mayberry sheriff's department telephone works and then she instinctively proceeds to lift the earpiece up.
Also the bonehead farmhands pull up to the angry mob in an unbelievably good conditioned automobile roadster that is not a '47 model. Very Great Gatsby looking here.
And in this '67 episode, Professor Robinson exclaims that man first lands on the moon in '70. Pity he couldn't have just opted to tell the local yokels that man would land on the moon in about a dozen years or so and leave it at that.
Yet strangely, this episode for these faults (the hillbilly mob is unforgivable but easy to overlook) stands above the rest, mainly for the mood and effectiveness with the music, the show's stock music, yes.
And Smith brings it all home when his second-in-command offers to drive him back to Chicasaw Falls, Smith's believed hometown.
Definitely an episode that is proof the show was trying to recapture some promise lost with competing to Batman's campiness or evidence the show wasn't deteriorating that badly in competing with Batman.
Wonderful episode of Lost In Space that is a classic from start to finish.
Irwin Allen's The Time Tunnel had just been axed so Irwin decided to shift time travel plots into LIS season three and Voyage to the Bottom of the Sea season four.
A couple of nice elements of LIS episode The Derelict used here: the full scale Jupiter 2 and the same music is heard sometimes.
A very rare photo exists, taken from the air when a chopper was flying over Fox in 1967, of the full-scale Jupiter 2 sitting in the Fox backlot...all set to film Visit To A Hostile Planet. Join a LIS Facebook group to find this photo.
Anyway..I have heard of a few 'casual fans' who remember LOST IN SPACE from their childhood who mention this episode as one they recall as a very favorite. It certainly IS an episode that can be easily remembered years later. I have also heard other fans who like to 'dis' this episode for being a bit too 'goofy,' 'silly,' or whatever, as far as the local Green Acres-like townsfolk are concerned. To those fans, I will say what I usually say (or think) when the same people like to 'dis' Season Two in general for being too silly or goofy.."Get over it!" This far into the series is surely a far cry from the good old B&W days, so you take what you can get. This episode is also a good example as to why I would never use 'silliness' as a yardstick in grading episodes. It has probably a bit more 'silliness' than the previous episode, the season kickoff, "Condemned Of Space," yet it is a notch or two better.
In one of the old videos about the show (perhaps LOST IN SPACE FOREVER, 1998), June Lockhart, while narrating, called this a 'defining moment', or a 'big moment' for the Robinsons..landing back on Earth and all. I would agree. Besides an excellently written episode from Peter Packer, and an excellently directed episode from Sobey Martin (whom we had only heard from just one time in Season Two since the B&W glory days), probably the two things that stand out and make this episode a huge winner for me is the excellent and very interesting outdoor location shooting, and especially the almost chilling, great and final wrap/finish to the story, as we first get a glimpse of the Jupiter 2 spaceship flying through the blue sky, and then rising through atmosphere (right after Stacy and Craig's exchange about flying saucers) to get away from..earth! This episode had one of the very few (four of them) really good endings to a Season Three episode. I will note the others when they come up. Yes, the ending to this episode can actually send chills up and down my spine. I certainly cannot say that about many colored episodes for sure.
Speaking of Craig (Robert Pine), if you look at his credits at IMDb, you will notice that this appearance in LOST IN SPACE was just about the very first thing he did..pretty much the beginning of his career.
