Sound effects, too. Took WBill Jr. to see it. At the beginning of the movie, when the Germans touched off the MG, the sound effect was directly over our right shoulder, at near actual db levels, and my son nearly jumped out of his skin.
Neat, sez me, and I'm sure that's what the director was going for.
I was in the front with the large screen.
It was as though I was in it rather than watching it.
