One thing we were all in agreement on from the start is that we didn't want to do a slasher movie. [. . .] I became very excited when we decided to make the world at large, in the service of death, our antagonist. Everyday objects and occurrences then take on ominous proportions and it becomes less about whether or not our characters are going to die and more about how they will die and how they can delay their deaths. The entertainment value is in the "ride" not in the outcome, and by placing the premise of the film on the inevitability of death, we play a certain philosophical note.
