In a story from Variety, it seems that the score for The Dark Knight will not be able to compete for an Academy Award.
The score was taken out of contention "by the executive committee of the Academy music branch."
Hans Zimmer and James Newton Howard are expected to officially find out the bad news within the week.
It turns out that there were "five names" saying that they were composers on the music cue sheet which is too many for the Academy apparently. Even with fellow composers Alex Gibson, Mel Wesson and Lorne Balfe signing an affidavit that "the score was primarily the work of Zimmer and Howard" that wasn't enough for the Academy and the score was disqualified.
