It's Been Done

A few months ago, I suggested:

I'm waiting for a movie in which an incredibly-cute kid turns out to be a vampire … unless it's been done.

It was called Låt den rätte komma in. It came out a couple of years ago in Sweden and an English-language version called Let Me In is about to escape. (I think that's a better phrase for this type of movie than “about to be released.”)
