Some new news about the elusive Doom Movie can be found here at comingsoon.net. Apparently Warner Brothers dropped its option to make the movie, and Universal has picked it up:
Universal Pictures has optioned Doom for producers Lorenzo di Bonaventura and John Wells, with Enda McCallion attached to make his directorial debut, reports Variety.
The script, originated by Dave Callaham, is adapted from the plotline for the id Software and Activision video game "Doom 3," slated for release July 15.
The story is set at a Mars space station, where an aerospace conglom is conducting secret experiments when something unleashes a demonic force that threatens to overtake the facility.
I guess you don't need to go to the article now, since that's the entire thing, so instead you should learn all about how your computer is going to kill you. And yes, the July 15th thing is interesting, but I suggest taking it with a grain of salt until there's some sort of formal announcement from id or Activision.
EDIT: According to this, the movie rights have not been given to Universal, but have instead reverted back to id.
