If he made either, Nolan would have my attention.

I am really intrigued by what kind of story he would tell if he did a western. If he could re-team with Wally Pfister, just think of the scenery, Wow! Maybe if he did it in time he could use Clint Eastwood in a role.

I reckon Nolan could pull off a Horror/Drama, something in line with The Exorcist.

But realistically, he would be more ought to direct a Western.
