Mark Hamill did a couple episodes in the second season of SeaQuest
Oh yeah…

Just kidding, I remember enjoying ‘seaQuest DSV’ at the time but I suspect it’s probably one of those shows that it’s best to not re-watch now and let the memory stay golden.
It was amazing how fast they went from being a straight “science based” show to plots straight out of Voyage To The Bottom Of The Sea. (Before lurching back to being “serious” again in the third season.) Irwin Allen probably would have sued if he wasn’t dead at the time. The environmental messages were often about as subtle as a boot to the head. I laughed my head off at the premise that beef was illegal in the future. The beef lobby is more powerful than some third world governments. 😉
Interesting we’re less than a year away from when the series was originally set.
