Broadbent in Potter
Jim Broadbent has secured the role of Slughorn in Harry Potter and the Half-Blood Prince and he's been talking about his role online.
"He's called Horace Slughorn. He's a retired teacher of magic who's drawn back out of retirement because he's got some secrets they need in the battle against the Deatheaters and he's quite star struck as a teacher and he's drawn back into the fold because he likes to notch up celebrity students, and he's drawn back by Harry."
From a non-Potter reader point of view I think it's another strong casting of a great British actor. The Potter series is giving British talent the most work they've had in ages, and some of the highest profile roles.
