Friday Box Office: Half-Blood Bank

It wouldn't require much magic to foresee Harry Potter and the Half-Blood Prince crossing the $100 million mark by late Friday, though the boy wizard may need a whole new spell to regain the momentum that can boost the franchise's sixth entry to the $170 million five-day most of Hollywood forecast for it. Holdovers Ice Age 3 and Transformers 2 kept a safe distance in second and third place respectively, but pity poor Bruno, which is on track for a 70-percent drop from its number-one opening last week. Blame the Irish, I suppose.
