Re: Hans Zimmers: Scoring Bats vs Supes AND Batman?
I think if Zimmer ends up not scoring this film, I'm pretty sure whoever is will be 'encouraged' to reference or work in "Flight" into the main underscore.
Zimmer is a big name commercially, just as big as John Williams or Elfman. Powell would be a great choice to score this film, should he decide to do live-action again, but he tends to write his own themes.
For example, when Powell did X-Men 3, he wrote his own themes but kept it stylistically in the same family. Same thing with Elliot Goldenthal and his scores for Batman Forever and Batman & Robin.
