May Days of Melies - The Apparitions [Le revenant] (1903)

Comical "ghost tale" by Méliès that uses the blurred, out-of-focus superimposition trick to creepy effect. Also of interest is the subtle symbolism invoked from the lodger's rebuffed advancements towards the maid, followed by the candlestick that won't sit still, grows much larger, and distracts until its flame finally seizes the man's full attention.

May Days of Melies - The Infernal Caldron [Le chaudron infernal] (1903)

So much to enjoy and appreciate in this one: the striking colors (especially the flames and demon green), the devilishly macabre subject matter, and the Méliès special effects. The coolest tricks involve fireball spirits that become ash and the use of out-of-focus superimposition to create the most visually-impressive ghosts in film up to this point.
