I really hope Powell returns to collaborate with his former mentor. I think both of their voices come through on the first two scores, and the results are wonderful. Alas, it seems that Powell is mostly out of the film scoring game for now, it seems.
Well, the headline doesn't alter the fact that the piece clearly refers to Zimmer as "co-composer" on the first 2 movies, and clearly identifies his collaborator as Mr. Powell. Further, it states there's "no word yet" about whether Powell will participate on #3. Is there any reason yet to expect that he won't? I hope not, though I know nothing about the trajectory of Powell's career. I only know I enjoyed the first two scores and hope the new one will be at least as good.
