Le Chaudron infernal
The movies Meliès did before 1903 were often pirated by  American producers. This is especially true for his popular movie A Trip to the Moon.  To fight against this product piracy, Méliès opened an American branch of his Star Film Company. He began producing two negatives of each movie he made: one for home markets, and one for foreign release. To produce the two separate negatives, Méliès built a special camera that used two lenses and two reels of film.
