Based on Jules Verne's fantasy adventure we follow Professor Lindenbrook and his motley posse into the bowls of the earth where they discover a land that time forgot (or something very similar). Very bad baddies, huge ravenous lizards, and giant mushrooms are just a taster of the goodies on offer. There's also a bit of effective sexual symbolism, in typical Hollywood style, which greatly enhances the syrupy romantic subplot. Excellent and with the added bonus of the late, great James Mason.
