What can Joel and Ethan Coen do? Better ask what they can't do. This dynamic duo is a film-making machine, with honors including an Academy Award for Best Adapted Screenplay for turning Cormac McCarthy's No Country for Old Men from a novel into a movie script.
Critics have said that the Coens' script for No Country is one of the most loyal adaptations ever written—and when you're talking about a novelist like Cormac McCarthy, that's a good thing. They may have tweaked a few things in the movie's focus, but the Coen brothers are smart enough to know when to leave a good thing speak for itself.
