I read a tweet by AnnaSophiaFan11 which alerted me to the fact that there is a page for Vampire Academy on IMDb. This is standard practice when a movie is in development. It doesn't necessarily mean that there is going to be a movie (even though I'd say there's a big chance when it comes to Vampire Academy, partly because of the ongoing vampire trend, but mainly because the books are so amazing).
If you want to see the IMDb page that's been created for Vampire Academy, you can go here. Most of it is not available unless you have an IMDb pro account, which I don't, so I can't tell you what the details about the movie are.
If anyone happens to have an IMDb Pro membership and is able to see the details for the movie, it would be very interesting to know what it says. :-)
