Helen McCrory to play Narcissa Malfoy in HBP

CBBC Newsround reported today that actress Helen McCrory has been cast as Narcissa Malfoy in the Harry Potter and the Half-Blood Prince film. Helen was originally cast as Bellatrix Lestrange in the fifth film, Harry Potter and the Order of the Phoenix, but had to pull out due to the fact that she had become pregnant during production (she was, of course, replaced by Helena Bonham Carter).

Newsround also reports that cast announcements for Lavender Brown and Tom Riddle will be released very soon.
