Well considering that Konami provided direct input on the movie and the director is quite well known and has some good credit to his name, silent hill fan to boot i think the movie will be one of the better if not best VG to movie translations. Those pics are production shots without all the film processing and lighting on it so yes they will be brighter. They seem to have captured the look,feel and idea behind Silent Hill very well even down to the hell world bits.
This i WILL se in theatres, RE3 i will wait till it comes on tv.
