Kinda tricky though, I mean nothing really happens in the 'Log of the Demeter' except for the fact that people are disappearing (hence the Alien namedropping).
Which basically means that the script was done, adding stuff would be risky. On the other hand what it needs is an amazing director with a great sense of mise-en-scene … something you just don't find much these days. And I not sure Marshall is the man for the job.

On a side note: IIRC there are no survivors on the Demeter in the novel, the captain is dead, strapped to the wheel.
