I know nothing about this, but I somehow don't feel Rozsa would've been a serious Huston choice. He used him only once, in 'Asphalt Jungle', and couldn't get him tranquilised enough, though Alain Resnais managed it later in 'Providence'. He admired his work, but thought it overwhelmed some pictures, which is okay if the film is grim, but not so good when there's subtlety in the mix. His attitude to Rozsa is supposedly summed up by a succinct quip: 'I would never direct a Rozsa picture', both a compliment and a criticism.

Huston disliked cliche, and the thing about 'Bible' is that it must deal with not just an epic story with leitmotif but also some very primeval and primal concepts like cosmic creation and destruction, better served by a very impressionistic sometimes minimalist technique. Chaos out of order needs more than melody. I don't say Rozsa couldn't have done that, but it wasn't his usual 'Sodom' biblical style. It's an episodic tale and the waltz of God works well, if somewhat daringly.
