There's no getting around the fact that No Country for Old Men is a violent movie. Within the first five minutes, you watch Anton Chigurh strangle a police officer with the chain of his handcuffs and kill another man with an air-powered needle gun. You won't find much shocking in the way of sex or romance (seriously, this has got to be one of the least sexy movies out there), but there sure is a lot of blood.
