Blooper: As impressive as the stop-motion animation is, it's still not without its occasional goofs. Some are rather minor and very unlikely to notice (and can even be Handwaved as events and actions that happen offscreen). Others, not so much. A few examples...
During the scene where Victor accidentally "marries" Emily, he places the ring on her index finger. A few shots later, the ring has somehow moved to her ring finger.
Victor receiving a gift box containing his dead dog Scraps. A couple shots after Scraps appears and reassembles, said gift box mysteriously disappears.
A very glaring one right at the beginning of the film involving Lord Barkis' entrance. During the opening sequence, as two old men greet each other and walk by, Barkis... appears out of nowhere.
Doing It for the Art: The various figures used in the film were animated using a very intricate clockwork system built inside of them, replacing the stop-motion industry standards of using multiple expressive heads.
Fake Brit: American Johnny Depp as Victor, Victorian British gentleman.
Bonejangles doesn't just sound like Danny Elfman, he even has shades of his appearance and mannerisms.
Playing Against Type: Anyone who is introduced to Johnny Depp via his role in this movie as the shy and soft-spoken Victor Van Dort will be surprised to find that he usually plays characters that are practically the exactopposite (a good example being Jack Sparrow).
Talking to Himself: Completely averted. Despite a good number of minor characters having the same voice actor, none of them speak to each other. For example, Mayhew and William Van Dort are both voiced by Paul Whitehouse and have some interaction together but never say a word to each other.
What Could Have Been: As stated on the main page in the Ink-Suit Actor entry, Helena Bonham Carter was originally going to voice Victoria. She asked to voice Emily instead, since she already played characters similar to Victoria in live action.
