Also known as "The Fabulous Journey to the Centre of the Earth" in the UK. The film is partially dubbed in English, but it has good cinematography.
As in the original novel by Jules Verne, four people try to get to the center of the Earth by entering into a world of caves through a volcano. On their way they discover, among other things, prehistoric animals such as some dinosaurs and a giant gorilla-like ape.—Volker Boehm
