According to Casting Call Pro, five new actors have been cast in Harry Potter and the Half-Blood Prince, some of whom might just be extras in the film.



Lord Johnpaul Castrianni is listed as playing a Death Eater.




Katy Newman-Wood plays a Hogwarts student (she had the same role in Order of the Phoenix).




Guy Mannerings plays one of teenagers in the Slug Club.




Nina Voelker will play a new and original character named Wendy Slinkhard.

We await confirmation from Warner Brothers.
