There's a DOOM movie story on Dark Horizons, reporting from the set of the movie in Prague (thanks Blues News). In case you were looking for a movie taking place on Mars, with monsters coming from hell..well, look elsewhere.
The monsters have nothing to do with hell, the plot is not taking place on Mars and "space marines" are not well "space marines" as their outfits are more like SWAT team members. The story follows eight marines, teleported into a command centre of a secret base on a remote planet. There, they learn that something strange is happening and soon monsters start to appear. The monsters aren't from hell, but rather people mutated by some nasty super-virus although the monsters look very similar to those in the game. [...] There will be loads of shooting though, especially in the end where a large number of sequences will be shot purely in "first-person" perspective of the leading character (Karl Urban). The chainsaw and Bio Force Gun do appear in the film.
