. . .the scene in the gas station is quite remarkable on a few levels for me. First and foremost I think we not only learn that this man is completely insane but also completely dedicated. A scary combination when dealing with a killer. His last line he utters to the bewildered clerk is haunting and hilarious at the same time, he virtually has the guy "making" in his pants and yet then he drops in a bit of humor or at least as much humor as this man is capable of. It's a great line. . . .
IMHO, the best scene in the whole film is the bit at that remote gasoline station and the best actor in the movie is the old guy playing the station owner. The actor playing the killer plays it so low-keyed that the only animation in the scene is the station owner. The scene wouldn't have been the same without him, because he's spot on as an old man just passing through life doing the best he can. The killer is nuttier than anyone we'll ever meet so we don't know him. But, thanks to that particular actor, we know the old confused station owner.
My second favorite character is the fat lady running the trailer park. That boy may be a dangerous killer, but she's not breaking the rules for him or anybody else.
In the end I think what is so fascinating to me is that I think this movie is all about a social commentary of our world today and yet it is set in the 80's and again that to me just shows us once again how truly brilliant the Coen's really are.
Well, that's one possible interpretation. But as you live longer, I think someday you'll look back and say 2008 wasn't really all that different from the 1990s, the 1980s, or the 1970s. Maybe not all that different from most of the 1960s either. What was true about the big issues of the 1970s, 1980s, 1990s, is still true today.
And now to finally take a stab at your questions Tatty, I have no idea why he took his socks off. It made perfect sense at the time.
I'll go with whoever's earlier guess that he didn't want to step in blood. You'll remember he checked the soles of his boots after the last killing. I think it was more of a phobia than anything. Had he stepped in blood, it would have left a clue, but he doesn't try to clean up the blood because he's not worried about leaving clues. He is worried about getting blood on his feet, however.
