At the San Diego ComicCon there was a Doom movie panel, apparently. Any attendees got a glimpse of a 90 second trailer for the movie and a second unfinished piece as well:
The teaser trailer had a lot of quick cuts of The Rock; Karl Urban and the rest of the cast along with brief looks at the monsters, the environment (and they look right out of Doom 3, by the way; right down to the computer screens on the base) and battles with the monsters. The second clip is the one that got the most reaction; part of the first person shooter sequence featuring Urban’s character. Yes, the movie will at one point have a viewpoint just like the game, right down to the weapons loading animation.
