Apparently, Kevin Smith had a fairly typical reaction when asked by Mark Steven Johnson if he'd like to direct an episode of PREACHER - fear.
"Yeah, he asked me if I wanted to direct an episode of 'Preacher'; which I thought was pretty kind of him; but, I don't know if I'm up to that. I love that book so much, and being able to translate one of those books to the screen, I don't think that's me. 'Cause you don't want to be the guy who f**ks it up, and so I was like, 'Well, I don't know, we'll see.' But I'm certainly not committed to do it, only as much of I don't want to drop the ball 'cause I like it so much. But if it was some show I didn't like; I mean, I've never really directed TV anyway, so it's kind of difficult getting my head around it, but since it's an hour-long drama, presumably, I'd be more keen to directing a movie rather than TV – I don't know, maybe, maybe. The thing that would keep me from doing that would be I'd be afraid of ruining what I like so much about 'Preacher' – so we'll see if that happens."
I dunno - Smith could probably direct a fairly decent episode of Jesse and Cassidy sitting in a bar talking shit. That's pretty much Smith's whole career as a film-maker, surely?
