QFT.
In an interview that Matt Reeves gave at SXSW that recently surfaced, he was asked obliquely about this topic and he had this to say:
Well, you know the thing about it is… I don’t want to give anything away just yet. You will see when you see the movie, but I have tried to remain as true to the story as possible, but you guys will tell me!
When asked about what rating the film might get in the US, he went on to say
I said “If that turns out to be the case, I think it just means that there’s a different cultural response to it, because in the United States, I cannot imagine the film as we have done it getting anything other than an R.” I just can’t imagine it. Now if it does, I’ll be surprised. Let’s put it this way, there was no attempt to try and soften it to make PG-13.
I'm certain that he could not even hint at Abby having been a boy and get anything less than an R rating. So maybe this question is still open. Could he and Chloe make it believable that Abby could have been a boy? I am dubious, but such things have been pulled off before.
