I think the Ti comes through prettly clearly -- his quibbling on the logical genre categorization of "Shawn of the Dead", for example, or his very logical answer to "If you were a zombie, who would you eat first?"

Furthermore, his style of movies and the overall "vibe" I get from him doesn't seem Beta to me. So that leaves Alpha NT.

I would really have to view other interviews and things with him to nail it down to my own satsifaction, but ILE doesn't seem out of the question.
