I still watch that show occasionally now and always laugh at that huge front window in front of Nelson's study.
But don't forget those huge mechanized curved doors that slid over those giant curved glass view-ports for when the Seaview had to ram those giant sea-weed monsters that looked like giant men in seaweed costumes.
I saw one the other day where seaweed men were created by a formula: get this, seaweed and radiation and a formula created by an evil scientist (I just hate them);
and one of the seaweed men monsters was roaming the roomy passageways beating up crewmen while the other was a huge giant who looked the same as the small one but big and was punching the Seaview from outside, BOOM.
And evertime he hit it BOOM they would roll the camera from side to side like in Lost in space and then men inside the tub would act like it was the Seaview rolling from side to side.
What a classic LOL
Now I'm going to have to search. I had no idea it was still on tv somewhere!
LOL!
I notice that the Seaview always seemed to be bucketing along at about 30 knots with bubbles from...somewhere...boiling out of her and pinging constantly with active SONAR. Every Babushka sleeping in bed in the Soviet Union had a solution on the Seaview at all times.
