Acteur Jim Broadbent (Hot Fuzz, Moulin Rouge!) liet in een interview met DarkHorizons weten dat hij is toegevoegd aan de cast van de zesde Potter-film: Harry Potter And The Half-Blood Prince, waarvoor de opnames deze week van start gingen. De Brit zal de rol op zich nemen van Horace Slughorn.

"Who am I? 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."
