Dark City from 1998, one of the most innovative and compelling science fiction films ever made. Aliens build a changeable experimental city and populate it with humans in order to study them. The films tag line was: They built the city to see what makes us tick. Last night one of us went off. In the movies most salient scene the protagonist states: You know, I dont think the sun even exists in this place. Jennifer Connelly, Kiefer Sutherland, and William Hurt give fine performances.
