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.
Trivia: Reportedly, Disney chairman Jeffrey Katzenberg repeatedly tried to sabotage the film's production as he was worried it would overshadow their film "Aladdin," especially as both films featured Robin Williams as a prominent character.

It's believed this may have been a factor in William's feud with Disney that lasted several years after "Aladdin" was released.
