One possible direction being mulled over is to pick up with Shauna Macdonald's "Sarah," that is, if she didn't croak at the end of the first film. "Shauna just had a baby so she's not gonna be ready to film for a bit," Marshall adds, then, "['De2cent'] is a ways off." But there is palpable interest coming from his former leading lady. "She wants to continue the journey a bit more. As far as I'm concerned, there's only one way to take her character, she has to die. If we didn't kill her at the end of the first film, we have to kill her at the end of the second one," Marshall laughs. "So, I don't know - I don't know where we stand yet."

I just watched Descent last night. Anyone else get the feeling that maybe the creatures didn't really exist, and they had all gone mad (especially Sarah) and started killing each other, hallucinating each other to be monsters? It would add new meaning to the title. 'Descent' could represent their descent in the cavern and their descent into madness as well.
The scene were they are examining the corpse of one the monsters is a pretty strong argument against that interpretation, though.
