There are still some people left for sorting in the last past of the movie! Well, technically she's not a new member of Ravenclaw, just a new cast member on role. Actress Kelly MacDonald will be portraying the role of the Grey Lady, the resident ghost of Ravenclaw house.
For those of you who have read the Harry Potter books, you'll be familiar to the part played by the Grey Lady. But in case, you're one of those casual fans of the series, I'll give a brief :
In later half of the final book we see that Harry Potter needs some information to complete his task of life. In this course he comes to know that the Grey Lady is the daughter of one of the founders of Hogwarts, Ravena Ravenclaw! The ghost of Grey Lady then tells him very important information which helps him in his endeavor.
"Though the role is small, its very essential to the plot",Kelly quoted.
Th Grey Lady was murdered by the Bloody Baron, who killed himself out of regret. The Bloody Baron was the resident ghost of Slytherin house and was supposed lover of the Grey Lady. These ghosts had been seen once in the first movie when Harry Potter first dines on his house table. The role was then played by Nina Young (Clash Of the Titans).
Hope you all keep up with these latest news form Harry Potter's world!
