The only thing better than being a sex symbol, like Scarlett, is being a nerdy sex symbol who got her big break in the adaptation of a children's novel, like Emma. So now you know why ScarJo is rocking the short hair, stern glare, and very little clothing.
Who do you think looks better with short hair? We're tempted to say Emma, but our memory of her hair is really a memory of her nipslips. Likewise, if we were to deem Scarlett the winner, it would only be because of her gorgeous legs and hot prizefighter shorts. Only now do we realize that hair length is completely unimportant.
