The Impossible Voyage (Voyage à travers l'impossible) is a 1904 silent film (produced by Star Film, France) by pioneer filmmaker Georges Méliès. The film's time is about 20 minutes (nearly five times the length of the average film at that time), and probably was inspired by Melies' successful earlier film Le Voyage dans la Lune (A Trip to the Moon). It is loosely based on Jules Verne's play Voyage à travers l'impossible. Like most of Méliès' films at this time, it made use of narrative, models, and trick photography.

At the royal court, a prince is presenting the princess whom he is pledged to marry when a witch suddenly appears. Though driven off, the witch soon returns, summons some of her servants, and carries off the princess. A rescue party is quickly organized, but the unfortunate captive has been taken to a strange, forbidding realm, from where it will be impossible to rescue her without some special help.

The background of this picture represents a scene along the beautiful river Seine in Paris. A gentleman enters, and taking a blackboard from the side of the picture, he draws on it a sketch of a novelist. Then, standing in the centre, he causes the living features of his sketch to appear in the place of his own, which is utterly devoid of whiskers. The change is made so mysteriously that the eye cannot notice it until one sees quite another person in the place of the first. Again another sketch is shown on the board, this one being that of a miser; then an English cockney; a comic character; a French policeman, and last of all, the grinning visage of Mephistopheles. It is almost impossible to give this film a more definite description; suffice it to say that it is something entirely new in motion pictures and is sure to please.

One of the greatest of black art pictures. The conjurer appears before the audience, with his head in its proper place. He then removes his head, and throwing it in the air, it appears on the table opposite another head, and both detached heads sing in unison. The conjurer then removes it a third time. You then see all three of his heads, which are exact duplicates, upon the table at one time, while the conjurer again stands before the audience with his head perfectly intact, singing in unison with the three heads upon the table. He closes the picture by bowing himself from the stage.

A band-leader has arranged seven chairs for the members of his band. When he sits down in the first chair, a cymbal player appears in the same chair, then rises and sits in the next chair. As the cymbal player sits down, a drummer appears in the second chair, and then likewise moves on to the third chair. In this way, an entire band is soon formed, and is then ready to perform.
