Got ahold of both King Solomon's Mines and Allan Quatermain and the Lost City of Gold. The Richard Chaimberlain/Sharon Stone Indiana Jones craze cash-in films from the mid-80's.
Yes, they're B quality cinema. Yes, they retain quite a bit of H. Rider Haggard's racist views (although in both books upon which these movies were based, he's actually fairly progressive for his late Victorian times...). But they sure are a lot of fun, if memory serves.
Maybe the nostalgia bug will bite me in the ass after watching them, and I'll see them for how terrible they really are. Or maybe I'll sit back and enjoy a nice pair of evenings with the wife, after the little guy's gone to bed, basking in the campy fun.
Either way, I expect this to have an effect on my ideas for cool 'specials' to add to my megadungeon.
