As core members of the original cast namely Daniel Radcliffe, Emma Watson, and Rupert Grint recently confirmed their return for "Harry Potter and the Half Blood Prince", what remain to be questions are surely the new names for the lineup.
Bringing an early speculation to this matter, LaineyGossip has come up with a tidbit saying that Naomi Watts may up for the role of Narcissa Malfoy nee Black, the wife of Lucius Malfoy and mother of Draco Malfoy, in the sixth installment of the mega-hit series. Also the sister of Bellatrix Lestrange and cousin of Sirius Black, the character is said to have a key scene at the beginning of "Prince."
The site further mused that Watts' recent claim of feeling more British than Australian is presumably intended to warm J.K. Rowling up to consider her for the part as the author has been known to prefer having British actors in the cast of the film adaptations of her "Potter" books. Since no official announcement made, please stay tuned for more info and updates about this subject.
