I have a question... Why did Tifa cut her hair short? I mean in the game, her hair is like knee long but in the movie, it's shorter. Did her hair bother her? I know it's a stupid question but can anyone give their opinion on this?

Oh and um regarding Cait Sith, where's the giant stuffed mog he 'magically' brought to life? And in the end of the movie, Marlene is holding him like a doll. Is he a doll?
