What timing. I was just getting ready to bump this thread myself and see if anyone had any updates.
I just finished reading the book "Heaven & Hell to Play with, The Filming of Night of the Hunter", and it was a very interesting & detailed account of the filming. It made me all the more eager to see a new S.E. along with some of the outtakes and home videos shot on the set. Apparently, Laughton used a technique where he kept the cameras rolling at all times, and in between takes you can hear his directions, etc...
