Valley of the Dragons
Two men preparing for a duel in 1881 Algiers, Irishman Michael Denning and Frenchman Hector Servadac, are swept from the face of the Earth by a passing comet and find themselves on another world with cavemen and prehistoric animals. They try to find a way back to Earth. (Servadac is the only one of 36 characters retained from the original novel.) The men are separated after an attack from a mammoth. Servadac finds refuge with the River People and falls for a beautiful blonde, Deena. Denning falls in with the Cave People, where he falls in love with brunette Nateeta. The two men are reunited rescuing the Cave People from attacking dragons with an avalanche. They persuade the River People and Cave People to stop fighting and settle down with their respective women. They vow to try and get on the Earth the next time the comet approaches in seven years.
