March Melies Madness! - The Triple Conjurer and the Living Head [L'illusioniste double et la tête vivante] (1900)

Méliès splits into 2 versions of himself, after which point the doppelganger interacts with the original (or is it vice versa?). A living, bodiless-head is produced and then turned into a full-bodied woman. Finally, the devil appears and ultimately reveals himself to be a 3rd Melies!
