Went to get something to eat after the screening so I just got back.
Theater was about 3/4 of the way full here in St. Louis. This was my first time seeing anything in IMAX and I have to say, I was impressed. The trailer looked so much better and more vibrant than on my computer screen.
I assume everyone knows by now about the extra 5 seconds of BM and SM charging at each other. It looked to me like SM was knocked backwards at first, then he gets his feet under him, and starts charging back. Then we cut to BM in his armor who starts charging at SM and then it stops when they are about to collide. It definitely looked like a panel from DKR the way their bodies were positioned. Totally sweet.
Still no sign of Wonder Woman. I guess she is being reserved for future trailers..
