There is a very brief (30 seconds or less) scene at the very end. SPOILER: The scene opens in the store Arcana Cabana, where we see the Mickey sorcerer hat under glass, then Horvath's hat, followed by a hand (Obviously Horvath, since we see his cane as well) picking it up and a roach left behind.
During the opening credits the sound effects of the Walt Disney Pictures and Jerry Bruckheimer Films logos are replaced with sound effects from the film (sounds of spell casting and Tesla discharge).
