I admit, I don't know a whole lot about the original source material for The Sorcerer's Apprentice. But the film is so fundamentally different from the short on basically every level, the only thing they seem to have in common is the same VERY basic premise, and that cleaning scene in the middle of the live-action film that comes off more as a homage than anything.
