Journey Through the Impossible Journey Through the Impossible (French: Voyage à travers l'impossible ) is an 1882 fantasy play written by Jules Verne, with the collaboration of Adolphe d'Ennery. A stage spectacular in the "féerie" tradition, the play follows the adventures of a young man who, with the help of a magic potion and a varied assortment of friends and advisers, makes impossible voyages to the center of the earth, the bottom of the sea, and a distant planet. The play is deeply influenced by Verne's own "Voyages Extraordinaires" series and includes characters and themes from some of his most famous novels, including "Twenty Thousand Leagues Under the Sea", "Journey to the Center of the Earth", and "From the Earth to the Moon".
