Below are a series of short videos from the director of Annabelle creation which gives you an overview of what way he operates as a director etc. There five parts in all which you can access through each video.
Its taken from the perspective of a director who was used to being essentially a one man operation doing everything from camera operation to sound design - something I can most definitely relate to - and suddenly being thrown into making a movie with a big crew and what that entails. As a baptism of fire I would imagine, at first, it was quite difficult trying not to want to do everything yourself. So essentially you would have to 're-train' yourself to fall in line with the hollywood way of making movies. I'm sure there was a few teething problems in this he briefly touches on that in the interview with Film Riot which I will link to on the bottom.
