Mark Goddard ... Maj. Don West

The inherent dangers of the alien planet continue as the Robinsons flee south to avoid the terrible, sub-zero deep freeze threatening them. Dr. Smith defiantly stays behind in the Jupiter 2 where he obtains peculiar orbital data. Initially delighted that the Robinsons are blindly heading to their doom, deprivation from human contact finally gets to the devious doctor and he sends the robot to warn them that they're jumping straight from a freezer into a frying pan. And a once-frozen sea becomes a tempest-tossed danger. Written by statmanjeff

Dr. Zachary Smith: [radioing the chariot] Turn back at once before it's too late. You're in terrible danger. You've got to believe me.
Prof. John Robinson: Smith, this is Robinson. Now why on earth should we believe you?
Dr. Zachary Smith: May I remind you, my dear sir, that we are no longer "on Earth."
Prof. John Robinson: Oh, that's very clever.
Dr. Zachary Smith: And unless you turn around and come back right now, you won't survive another hour.

The Hungry Sea
27 November 2006 | by miamivice1962See all my reviews

The Hungry Sea was my favorite episode of LIS. It was what the series should have been based on. Guy Williams(John Robinson) was the main focus of this show and it was much more serious and adventurous. There was a blooper in this show however. When the crew in the chariot thought Don West went overboard in the ocean, they did not realize he was just hanging over the side. How could they not see him hanging over the side when the chariot is made of glass windows all around? Anyway it was my favorite episode and I still to this day can watch season one and be entertained. Seasons 2-3 got to campy and went downhill because of DR. Smith IMO.
