The differences between the Grimm brother's magic mirror and Disney's are fairly stark. The mirror in the Grimm's version is mostly just that: a mirror. This mirror just so happens to have a voice and never tells a lie. Other than that it is perceived as just a mirror. The Disney version has a much more personified version of the mirror. It contains a mask surrounded by a veil of smoke from within the mirror. The mirror itself almost seems to contain another world. The mask itself is lit from underneath giving it even more of an ethereal effect. The mask's expression seems to move between comedy and tragedy, giving it yet another level of mysterious appearance. We need to ask ourselves why Disney would make these obvious and distinct decisions when he chose to animate the mirror. The unknown and constant fluctuation between tragedy and comedy lend the mask to take up an appearance of a shifty evil character. The light from below is that of fire, possibly implying that the mask is a spirit from hell. No detail of the mask that Disney added lends itself to being a good character. The mask appears as a tortured soul in the Queen's service. This is a fairly deep and twisted leap from for Disney to make from just a plain mirror.
