Of course after the loud explosion that destroys the shuttle and/or space station my son leans over to me and says, "Its in space so how would we hear an explosion? There is no sound in space." To which I felt stupid that a 12 year old had figured that out immediately while I had fallen prey to an age old hollywood fictional license. Grrrrr!!!
Apparently, they only did that for the trailer. In the movie, there's no sound in space.
That new trailer looks pretty damn impressive!
