- Beam Me Up, Scotty!: Contrary to what the trailers and DVD chapter listing will tell you, Chigurh never says "Call it, friendo"; they're in two different lines ("What business is it of yours where I'm from...friendo?"/"Call it.")
- Career Resurrection:
- It helped get Josh Brolin noticed again after a long down period in his career.
- This film was one for the Coens as well. After a seven-year period where their films were commercially unsuccessful, critically unsuccessful, or both, this film was their first after a three-year hiatus; it's seen by many as their magnum opus, and it created a new boom in their careers.
- Tommy Lee Jones, too. Though he never really fell off the map, he had a minor slump after a run of very successful films in the mid-90's, and while he had a few critically acclaimed roles inbetween (A Prairie Home Companion, The Three Burials of Melquiades Estrada), they weren't major hits or award-winners, and this role brought him back to the forefront. He was also in In the Valley of Elah in the same year, which solidified his comeback.
- Dawson Casting: Carla Jean is a teenage wife in the novel and is played by 30-year-old Kelly MacDonald in the film, though this could be more an Age Lift.
- Dueling Movies: With There Will Be Blood, which was being shot around the same time in rural Texas, note was also a Darker and Edgier film by (a) respected auteur(s), released around the same time by the same distributors (Paramount Vantage & Miramax) and competed for Best Picture at The Oscars.
- Fake American: Kelly Macdonald, who plays Carla Jean, hails from Scotland.
- Fake Nationality: Possibly-Mexican Anton Chigurh is played by Spaniard Javier Bardem.
- Follow the Leader: The Coen Brothers admitted they had to work hard to make sure the film was distinguishable from The Terminator.
- Reality Subtext: The book was written partly as the author's reaction to the sensation of escalating violence brought in by drug trafficking, starting in the early eighties and continuing to this day. To evoke this, the book and movie are Period Pieces. The author's response to this feeling can possibly be seen in the Uncle's speech near the end, when he outright states that things are not worse or better than the past, they just always feel that way to those living at that moment.
- The Red Stapler: The demand for silenced, pistol-grip shotguns increased as a result of Chigurh's primary weapon.
- Throw It In!: During early readings, Spanish actor Javier Bardem attempted unsuccessfully to downplay his accent; the Coens liked the resultant mangled, unidentifiable dialect so much that they encouraged him to speak like that for the entire film, hence Chigurh's strange and unsettling accent.
- What Could Have Been: Josh Brolin got his role after Heath Ledger was offered it and turned it down.
- You Look Familiar: Tommy Lee Jones, Josh Brolin, and several minor cast members would also appear in In the Valley of Elah, released the same year. Both films were also shot by the same DP, Roger Deakins.
