Harry Potter and the Half-Blood Prince
Like James Bond, the Harry Potter movies just keep chugging along, immune to the outside cinematic world, ensconced in their universe of quidditch and muggles, inferi and death eaters. They have perfectly fitted their source material from day one: each arriving regularly with a thud on the doormat every year or so since 2001, achieving a near-institutional status that has eluded the Narnia adaptations.
There had been mutterings, however, over this sixth in the Potter series, pushed back from its original planned release date last Christmas. Monkeying with the schedule tends to alert the paying public that all is not well. The Half-Blood Prince is adapted from JK Rowling's penultimate novel, but so desperate are the producers not to compromise their revenue stream that the final book, the Deathly Hallows, will be divided into two parts.
