The reason we can't attain the highest level of knowledge while incarnate is that we can't then wholly escape the influence of the body (and so of perception and of certain desires that take us away from thinking properly); and that prevents us from understanding fully what forms are, which one must do in order to have the highest level of knowledge.

Had we had all the money in the world to spend and we were doing another studio movie, we probably would have jumped quickly into the Necromonger universe and done an Orpheus Descending movie there. We didn't have that kind of resource. So, we said, this time, "If not that, this time, then what is it? What does this new movie look like?" Quickly, just in talking about it very simply with Vin [Diesel] in his kitchen, we decided on a survival, left-for-dead story, where Riddick could, as a character, reclaim the animal side.
