ACCIO TRIBUTE! For being the world's highest-grossing film franchise in history (non-adjusted for inflation, in which case it would be the James Bond films, albeit with 3x the films), the Harry Potter series sure hasn't gotten any respect from the Academy. In sum, the eight films have received twelve nominations in total, none for acting/writing/directing, and zero wins. Alan Rickman, still, has never received an Oscar nomination in his life.
(By way of comparison, the Lord of the Rings trilogy received thirty nominations overall and won seventeen Oscars -- 4/13 for Fellowship, 2/6 on Two Towers, 11/11 for Return of the King.)
The series deserves better. Steve Kloves, J.K. Rowling, the actors, and the producing team deserve credit for an overall faithful, entertaining, family-friendly adaptation of a deservedly legendary series of books. They picked great kids a decade ago who matured into the actors they needed; the UK's finest thespians were well-used in filling out this world. When you consider how many adaptations fail to capture their source material accurately, the Harry Potter films cleared a high bar indeed.
So, with only three nominations this year, all in technical categories, what is to be done? I think an Honorary Oscar to commemorate the overall achievement would be appropriate, except those were already given out this year. (Make an exception!) Otherwise, at a minimum, they should at least do a three-minute tribute reel, then bring out the cast and behind-the-scene team for the long standing ovation they richly deserve. This is only common sense—not magic.
