Thanks to Entertainment Weekly for letting us know that in tomorrow's issue of the magazine a new picture from Harry Potter and the Half-Blood Prince will appear.
The new image shows Harry (Daniel Radcliffe) and Prof. Slughorn (Jim Broadbent) in a classroom.
According to the article:
Daniel Radcliffe's boy wizard has a new potions master — the guilt-racked Horace Slughorn (Jim Broadbent, pictured with Radcliffe) — in Harry Potter and the Half-Blood Prince, due Nov. 21. 'He's a good teacher,' says Broadbent, 'but he has a fateful weakness for charismatic, high-flying, brilliant students.'
