A new article on Kelly Macdonald in Vanity Fair has revealed that she will be playing the Ravenclaw ghost, the Grey Lady, in Harry Potter and the Deathly Hallows: Part 2.  A photo of Kelly may be seen below.

John Lopez: I hear now that Boardwalk’s done, you’re working on the final Harry Potter as we speak. They really are trying to get every U.K. actor into those movies.

Kelly Macdonald: It’s true! I’m friends with Colin Firth, and he told me he’s the only Brit who’s not in it.
