HBP casting

New cast members for Harry Potter and the Half Blood Prince... Naomi Watts (Narcissa Malfoy), Joseph Fiennes (I bet you anything he plays the younger Tom Riddle Sr. - being Ralph Fiennes real-life brother and bearing the strong resemblence), and lastly Stuart Townsend (I gonna say either Fenrir Greyback or Bill Weasley - leaning more towards Bill if they can get his hair color right.)
