If you liked dark city i would also reccomend Equilibrium. It was a straight to DVD but it is a very intersting movie.
Equilibrium wasn't straight to DVD. It was a very limited theatrical release. I know that it was shown in theaters in Luxemburg. I liked that movie. However, I found it slightly pretentious, and I didn't like the ending. There are no happy endings. Some of the sets had written "tight budget" all over. I'm looking forward to Kurt Wimmer's next project, a Vampire flick called Ultraviolet.
The last movie I saw was Underworld on HD-DVD. It had great gothic cinematography which looked especially beautiful on high definition. I even liked the story though some of the writing was rather TV standard which was annoying. The pacing wasn't quiet right, hence the movie dragged at times. Some of the acting was poor. I still have some hopes for the sequel.
