La terra dimenticata dal tempo

The survivors of a doomed World War 1 ship manage to board and take over the German submarine which sunk them. After a lot of disputing, the sub becomes lost and before long the enigmatic island of Caprona is sighted. Due to desperately low supplies the two crews, who call an uneasy truce, are forced to land the sub and find themselves in a world where prehistoric animals still live.

This is a well-made and highly entertaining film. Doug McClure makes a good hero and the other characters are also interesting and believable, the story is well-paced and the music is suitably atmospheric. The special effects are not always as good as they might be (the giant pterodactyl and the plesiosaur that gets shot at look decidedly fake). But the film is a classic and I certainly found it a lot more memorable and enjoyable than any of the recent dinosaur films.
