I wish I had the pashion for BoE and the rest of the Exile series like I used to have when I was a wee-er lad. I have no original ideas for the Movie, heh.
BUT, it COULD work out like a J.R.R Tolkien thing...first movie, Fellowship of the Rings. Second movie, the Two Towers.
First movie, conclusion to Escape from the Pit. Second movie, Chapter 1 of Crystal Souls.
Get my logic here?
