I have that double feature Blu-ray but have not ever watched Ship of Fools. Nor did I ever read the book. I've always had the distinct impression that what BK and Druxy said would be the case, but now I'm ready to enjoy it for all that's good about it. I've got to remember to take it off the shelf when I go downstairs, and then it'll eventually happen.
But the kicker for me was that BK had never seen Lilith. I hadn't, either, until that very Blu-ray came out several years ago and people on Home Theater Forum were talking about it. I watched and instantly loved it (but maybe that's overstating it, I don't know now), even though it seems like there might have been something a little off about it, plot wise or something. I might be confusing it with something else. I guess I'll have to rewatch that, too.
