The Hallucinated Alchemist (L'hallucination de l'alchimiste) 127 years old
The Flicker Alley DVD "Georges Méliès: Encore New Discoveries (1896-1911)" misidentified a partial hand-colored print of the 1906 film "Alchimiste Parafaragaramus ou La cornue infernale" (The Mysterious Retort) as this film, "L'hallucination de l'alchimiste" (An Hallucinated Alchemist) from 1897, which continues to be considered a lost film.
