Trivia: A little nod to another Blue Sky Studios Production, "Ice Age". When Rodney is looking around Robot city, he comes across a red robot that plays hip-hop. As Rodney walks away nervously ("Uh, n-n-never mind"), pause the frame just before the shot changes and you'll see (on the left) a yellow, mechanical Sid. Sid is the sloth (and the main character) from "Ice Age". (00:15:25)
Trivia: A popular film poster shows Emily and Victor reaching their hands toward one another. Emily's bony hand is on her right and Victor's suit and vest are backwards (note its buttons). Some say it was for legal reasons - Johnny Depp's name was supposed to appear on the poster first because of a contract, and they wanted the characters underneath the corresponding star names, hence the issue. Others say it was simply because the picture looked better with the bride on the right side.
