Trivia: After burning and exploding a car, Anton Chigurh enters in a pharmacy called Mike Zoss Pharmacy, to steal syringes, antibiotics and other stuff. The Coen brothers hung out at the real "Mike Zoss Drugs" when they were growing up and named it after him in the film as an homage. Mike Zoss Productions is the name of their production company (also named after the same man).
Trivia: Joel Coen and Ethan Coen share the record of four Oscar nominations for a single person for the same film (in this case, shared by the two) with Orson Welles' four nominations for Citizen Kane (1941) and Warren Beatty's for Reds (1981). The Coens' four nominations are for Best Picture (as producers with Scott Rudin), Best Director, Best Adapted Screenplay, and Best Editing (under the pseudonym Roderick Jaynes). Welles was nominated both Best Picture (also as producer) and Best Director, as well as Best Original Screenplay (won, and shared with Herman J. Mankiewicz), and Best Actor. On the other hand, Beatty was nominated for Best Picture (also as producer), Best Director (won), Best Original Screenplay with Trevor Griffiths and Best Actor.
Trivia: The credited editor for this film, Roderick Jaynes, is a pseudonym for Joel and Ethan Coen, who have co-edited all of their movies since Blood Simple (1984), (in addition to co-directing and co-writing them). New York magazine reported that they devised the pseudonym when Guild membership rules would not allow two co-credited editors on the same film. Despite his non-existence, Jaynes was nominated for an Oscar for editing No Country for Old Men (2007) (as well as Fargo (1996)), but he has never won one. Joel Coen told New York magazine that if Jaynes had won the Oscar, the award presenter and not the Coens would have been the one authorized by the Academy to accept the award on "his" behalf. Joel Coen explained that the Academy doesn't "allow proxies to accept awards at the Academy Awards, ever since Marlon Brando and Sacheen Littlefeather."
Trivia: While on location in Marfa, Texas, There Will Be Blood (2007) was the neighboring film production. While filming a wide shot of the landscape one day, directors Joel Coen and Ethan Coen had to halt shooting for the day as a gigantic dark cloud of smoke floated conspicuously into view. The source of this was found to be from Paul Thomas Anderson testing the pyrotechnics of an oil derrick set ablaze on the set of his film. The Coens had to resume filming the day afterward, when the smoke finally dissipated. Both this film and There Will Be Blood were the leading contenders at the Academy Awards a year and a half later.
