Contrary to popular belief, there are no living objects in the castle, this was made popular by Disney's animated movie. The original tale (Or, at least, a version of it) only said that there were talking parrots and monkeys as servants.
In the tale, Belle's father spends the night in the castle to rest and leaves in the morning, whereas he leaves immediately after having dinner in this movie. Furthermore, he begs the Beast for forgiveness after taking the rose and promises to come back in the original story. Here, he defies the Beast, forcing it to threaten his family.
Contrary to this movie, Belle's sisters don't show any remorse in the tale when their father tells them about the Beast's threat, but they immediately say this is Belle's fault for asking for a rose.
Perduras is a new character that was created for this movie only.
In the scene when Belle confesses her love to the Beast, they are both wearing red. Prior to this, they always wear different colors.
