Naomi Watts is set to star as Draco Malfoy's mum Narcissa in the next Potter film instalment, The Half-Blood Prince.
And she might be Australian by birth, but Watts will still fit right in with the Brit-centric cast - having stated earlier in the year that: "I consider myself British and have very happy memories of the UK. I spent the first 14 years of my life in England and never wanted to leave. When I was in Australia I went back to England a lot."
Which is all right then. Oh, and we expect the fact that she's perfect for the role also had something to do with her casting.
Voldemort's (well, Ralph's) brother Joseph Fiennes is also set to appear, as is Stuart Townsend. Who they'll be playing is mere rumour at the moment, but the book does feature an appearance from a young Voldy, so we wouldn't be too shocked if Joseph's currently practising his best hiss.
