Re: X-MEN: Days Of Future Past (Casting, Rumors, Pics till release)
That's true, of course. But it's pretty obvious that Olivia Williams was not supposed to be playing a 70 year-old Moira.
I don't think it's quite as black-and-white that Olivia Williams' Moira can't be the same person as Rose Byrne's Moira - mainly because I personally know some people who are getting up there in years but still look incredibly young (my mom, for example, looks much younger than she actually is) - but there's not really much to be gained by arguing about this issue.
Edit: BTW, after seeing the image of Rose Byrne side by side with the image of Olivia Williams, I actually think there's a very strong case to be made for the latter being the former's daughter, as there's a very striking physical similarity between them.
