James Mason is super in this adaptation of the Jules Verne story about a Scottish scientist and his rather motley team who set off in search of a long-lost Icelandic vulcanologist deep in the bowels of the Earth. I've been watching this film for thirty odd years now, and it is still a good, entertaining version of a strong fantasy story. Thayer David is good as the evil "Count Saknussemm" and there is even a duck to keep things in proportion as they combat each other and all sorts of prehistoric beasties on their journey. It's a wonderfully colourful and gently comedic treasure hunt...
