I really liked Justin Bells work in the pitch video. I was particularly impressed by the more atmospheric/ambient parts. Still, if they hired an external (and really famous) composer to work on the main theme, it would give the project much needed attention.
Plus, both Soule and Morgan are safe choices. If either of them writes the main theme it will probably be pretty awesome.
P.S. In my opinion, Inon Zur is vanilla.
