Composers he's worked with (he's not directed many films so far):
Steven Price (1)
David Sardy (2)
Graeme Revell (2)
We tend to hear about projects about six months out. They've either not selected somebody yet, or things aren't going well for the current composer and it's being kept quiet.
The new trailer for Suicide Squad was released today and lists Steven Price as the composer, so it seems Ayer has decided to continue his association with him from Fury.
The poster I spotted today still said Steven Price. With so many composers being replaced lately (Young for Dr. Strange & Grigorov for Tarzan), I'm actually a little surprised Price is still on board.
Hopefully, he'll deliver something unique & distinctive to the film & not just a zimmer temp.
