Harry Potter returns for his sixth year at Hogwarts.  There is a new teacher at the school, Horace Slughorn, played by Jim Broadbent, who proves to be very helpful to young Harry.  However, when Harry discovers the potions book that used to belong to the mysterious Half Blood Prince, he finds that his own spells and powers are enhanced.  Perhaps this will be the key to preventing Voldemort’s rise to power.  Daniel Radcliffe, Rupert Grant, Emma Watson, Michael Gambon and Alan Rickman return with David “Order of the Phoenix” Yates back in the director’s chair
