Every production is by faith, every single one. You can't do it unless you have faith because one, you never know if it's going to work, and two, if you aren't compelled and you aren't passionate, then you can't convince the studio to give you millions of dollars to make a movie and then spend millions more to market it.
Someone says, 'oh, you know what? I'm going to give you a shot to see what you can do', and you've been praying for a promotion, now someone gives you an opportunity, that's a miracle.
