The Curious Case of Benjamin Button

So I havent seen this movie yet, but from what Ive seen of the previews, it seems Brad Pitt plays a person who ages backwards, from geriatric to baby.

Im not sure, but from what Ive seen it looks like he might meet a little girl soon after he is first born, and meets up with her like half way down his life (conveniently when Brad Pitt is Brad Pitt, and the little girl an adult).

Anyway, it might turn out to be a bit soppy, but my imagination went running with different scenarios they could really play out if they would ever dare to touch the subject of pedophilia.

So this Benjamin Button, is Im assuming going to be of the appearance of a boy in his later, and supposedly wiser years.
No one would be able to deny that this person can consent to sex, given that hes clearly been around for a while.
Doubt theyll ever touch on the subject of this characters sex life, during the later years of the movie.

Anyway, maybe I should wait and see it before I comment to much on it.

Id be interested in hearing about it, if anyone has seen the movie already.
