This colorful, macabre feature is also something of an interesting change of pace from Georges Méliès. His impish wit is at its most morbid here, and while the special camera effects are used less lavishly than usual, this also enhances their impact. The hand-tinted color is still vivid enough to add to the overall effect, with the greenish demons and the brightly flickering flames helping to set a sinister atmosphere.
The brief story follows two demons as they toss three helpless captives into "The Infernal Boiling Pot", and then stir up the pot to see what comes out. The 'spirit' effect works particularly well, and the ghostly shapes show how versatile Méliès could be in varying his techniques as required. To be sure, the techniques used in much more recent movies have gotten us used to seeing effects like this, but for 1903 it is quite impressive, and it holds up very well.
It would be interesting to know how the original viewers of this feature responded to it, since its ghoulish tone and vivid images contrasted with almost any other movie of its day. In any case, it is still an interesting feature that is definitely worth seeing.
