I cannot help feeling that this was originally a remake of The Lost World which someone changed at the last minute. The plot is much closer to The Lost World and the early scenes look more like night time above ground action than underground. Take away the narration and the plot could easily be one where the characters emerge from a mine into a lost valley rather than a subterranean world.
Certainly this has nothing in common with the Jules Verne novel other than the title and the idea that everything takes place underground.
With a weak, nonsense-ridden plot( having just discovered an unexplored, underground lake would you immediately send all the men away and go bath in it ? ), poor screenplay, wooden acting, cheap effects( a series of stills to signify travel along an underground river ? - college students can do better ) this is definitely a modern B movie.
