Naomi Watts, Joseph Fiennes (brother of Ralph Fiennes, who plays Voldemort), and Stuart Townsend will join the Half-Blood Prince cast when filmimg starts in September. Naomi Watts will play the mother of Draco, Narcissa Malfoy. It is still unknown what roles the other two actors will play.
I pictured Narcissa Malfoy to be really tall, at least 5'10" and more snooty looking then Naomi Watts.
Anyone have any guesses on who the other two will be portraying? If a Mundungus is ever cast I vote for Bob Hoskins. He's looks exactly like what I picture Dung to look like.
Who knows? Just so long as they don’t cast Michael Moore as Slughorn.
Not guilty, though...
Naomi Watts -- a plausible Narcissa.
Her sister Bella is played by a 5'4" actress.
The Naomi Watts, etc. casting rumors for HBP are now being retracted on Muggle.net
Tony Robinson (Baldrick in the Blackadder series) would make a good Mundungus, I think.
