The Coen Brothers

While Fargo and No Country for Old Men are wildly different films, they do have many things in common.  The main characters (well, if you consider Jerry Lundegaard the main character in Fargo) are under quite similar circumstances, despite being rather different people.  They both have made a poor money-related decision and are trapped in some way because of it.  For Jerry, his scheme to have his wife kidnapped for money has backfired on him, and he is neither able to resolve the situation nor avoid being caught, so he is pretty much stuck.  For Llewelyn Moss, he has decided to take a case filled with 2 million dollars in cash from the aftermath of a drug deal gone wrong.  But Anton Chigurh will not rest until he hunts Llewelyn down, and so Llewelyn is trapped in that way.  Fargo and No Country for Old Men are both movies about the older generation unable to adapt to the younger, and folksiness, but I think they are also about greed and karma, as well as the absence of the concept of "good" and "bad."  Jerry and Llewelyn are driven by greed, and are punished for it; neither of them gets away with what they have done.  After all, Anton Chigurh is like the personification of karma; he follows the "sinner" practically to the ends of the earth to punish him for his greed.  He symbolizes malevolent, chaotic karma, while Marge seems to symbolize benevolent karma.
