When the 1985 Disney film The Black Cauldron was initially released to a test audience, many sequences were cut or trimmed after they found them either too graphic, scary, or violent. Some of the most notable cuts include the scenes of the Horned King's undead army, the Cauldron Born, killing some of his henchmen (after two are pounced upon, the men dissolve in a very graphic manner in which their skin bubbles and melts off their bodies, leaving a pair of skeletons behind). Another notable scene that was cut was that of a man's throat being slashed with a sword. Both cuts caused jumps in the sound track.
Recently, some cells of the melting men were obtained during an online auction, and a couple of years later these cells were inserted into footage of the released film (along with some missing shots featured in the trailer), which was then published on YouTube to show how the scene might have looked in motion.
Producer Joe Hale is said to own the fully uncut version of the film, though he has never released these aforementioned (or any other) deleted scenes to the public.
