Three years before opening, the film was test-marketed in the Long Island market as "Snow White: Happily Ever After". The test was unsuccessful and the film remained on the shelf before being reissued under its current title.
The film was originally produced in 1988 under the title "Snow White and the Realm of Doom," but Disney feared consumers would mistake it for a direct sequel to _Snow White and the Seven Dwarfs (1937)_ and filed a lawsuit, ultimately prompting a title change and several drastic alterations to the film's content.
In 1990, Filmation licensed the movie to First National Film Corporation for a June theatrical release. A dispute between the two companies, however, would delay its public exhibition for another three years.
When Batso is getting ready to blow out the candle, the part of the rope above the flame has been reduced to a single thread. When he turns around to talk to Scowl, the same part of the rope is a weave of many threads.
Just as Lord Maliss is going to turn Snow White into a stone figure, he ties her wrists together and behind her back. As the dwarfelles come to rescue her, we see a quick shot of Snow White gasping and covering her face with her hands, untied. In the next shot, she asks Thunderella to untie her, her wrists are tied together again.
When Sunburn shoves Scowl into one of the chain links for the bridge at the castle, we see that the chain is bare. But when she lets down the bridge for the other dwarfelles, the same chain has stuff hanging off of it as seen when the dwarfelles run by it.
