Bloomberg reportedly that “Harry Potter and the Half-Blood Prince” generated $159.7 million in sales in its first five days in U.S. and Canadian theaters, trailing “Transformers: Revenge of the Fallen” for the best such opening this year.

In “Half-Blood Prince,” Harry and his friends Hermione and Ron are menaced by the growing power of the evil Voldemort and his Death Eater allies. The film includes the death of a major character and big changes for the trio.
