A Victorian era scientist and his assistant take a test run in their Iron Mole drilling machine and end up in a strange underground labyrinth ruled by a species of giant telepathic bird and full of prehistoric monsters and cavemen. —IMDb
Film is actually pretty cheesy and over-the-top (though it's clear a lot of that is on purpose), but I give it an extra star for the awesomeness of Peter Cushing (in anything), the ungodly hotness of Caroline Munro and the great childhood memories. This movie really spurred my imagination as a kid!
