Ah, right, I'd forgotten about that. I agree, it seemed to me that was QT also. Even hooded, he somehow sticks out like a sore thumb.
And I agree about the scene, too. It was too slapsticky, suddenly shifting gears into the equivalent of an SNL sketch. Of all the rich situational things QT could've done with a run-in with the Klan -- that's what he settled on? I understand the satisfaction of demystifying them, but the bit about so-and-so's wife doing a shitty job with the eyeholes should've been a small, quick joke in the midst of something more fundamentally interesting, not the centerpiece of a scene where the heroes are forced to abandon their iconic carriage.
