Karel Zeman once again returns to the science-fiction fantasy world of Jules Verne, this time in a French fort in North Africa at the turn of the century.
A young lieutenant is saved from the sea by a beautiful maiden who has escaped from the ship of an arms dealer who brought her to a rebel Arab chieftain. When a comet approaches, their territory becomes separated from earth and flies off in space and into a new world.
Zeman appears already academic in repeating his usual effects but still shows such charm and inventiveness that the pic is still graceful despite repetitiveness and archness.
Colour is usually in tints but the special effects are impeccable.
