The Night on Bald Mountain sequence in Fantasia is probably the most extravagant piece of animated film making in regards to character animation and effects ever produced.
Fire, smoke, highlights and shadows, floating ghosts and experimental use of light, every single scene is loaded with awe inspiring richness. The result is definitely not family entertainment. This footage falls into the horror film genre. (I've said this before, terrifying enough to scare the popcorn out of kids). Disney in perhaps his darkest yet astonishingly beautiful animated moment.
The perfect challenge for young animator Bill Tytla, who had already established himself as an artistic powerhouse with gorgeous animation on several short films like Mickey's Fire Brigade and Cock o'the Walk. And the of course Stromboli in Pinocchio.
I don't know who drew Tytla's clean ups, but this work is exceptional. A devil in Art Deco line work.
What fascinates me even more are Tytla's rough drawings, even exploratory sketches. They give you insight into his extraordinary mind. The way he puts down lines to get a hold of this bigger than life character, his torso, arms, hands.
Many of the poses originate from the sequence director Wilfred Jackson own performance in front of the camera. Michael Barrier posted a few stills a while ago. Skinny as Jackson might have been, but you immediately recognize them as the inspiration for Tytla's masterful animation.
