Ooh, just heard that this was just reported:

Joseph Fiennes, Stuart Townsend and Naomi Watts are the latest addition to the 6th Harry Potter movie “Half-Blood Prince”.

It isn’t known yet what roles they’ll be playing, but my new plaid pants has some good ideas about it. I can easily see Naomi Watts playing Narcissa Malfoy; she was the only suitable actress I could think of that would pull Narcissa off (kind of drawing a blank on young blond English actresses, some help people?). Joseph Fiennes, being the brother of Ralph Fiennes who plays dark and twisty Voldemort, should definitely get the part of one of Voldeemorg’s relatives (grandfather, father, uncle? how old were they all supposed to be?). I think Tom Riddle Sr. (his father); didn’t Voldemort look like him?

But Stuart Townsend? Who’s he supposed to be playing? I looked up which (male) characters appear in book 6 and haven’t made an appearance yet in any of the films:

Fenrir Greyback
Marvolo Gaunt
Morfin Gaunt
The Muggle Prime Minister
Tom Riddle Sr.
Rufus Scrimgeour
Horace Slughorn
Bill Weasley

My guess for Townsend is Bill Weasley; I can easily picture him with red hair and I’d think he’d fit in the Weasley family. There are still some big parts that haven’t been cast yet (namely professor Slughorn). So, who do you want to see cast in the movie?
