Trivia
Elle Fanning's older sister Dakota Fanning also voiced a stop-motion animated film Coraline. Both The Boxtrolls and Coraline are nominated for Oscar in Best Animated Feature category.
This is the 7th movie in which best friends Simon Pegg and Nick Frost starred together. They both appeared in Shaun of The Dead, Hot Fuzz, Paul, The Adventures of Tintin, Ice Age: Continental Drift, and The World's End.
When the teddy bear's music box runs down, Baby Eggs hands the mechanism to Fish who gives the key only two half-turns. The music box then plays again, with its key somehow able to unwind for many revolutions. Later on after the Boxtrolls wake up, this impossibility is repeated, but is even worse since now the key winds/unwinds in the opposite direction.
