Trivia: At one point early in production, the film was going to be slightly retooled in order to make it the third entry in the "Cloverfield" franchise, following "Cloverfield" and "10 Cloverfield Lane." Eventually, this idea was dropped, and the movie was left as a stand-alone film.
Trivia: Julie Murphy, author of the the book "Dumplin'", makes a cameo as one of the cheering patrons at the drag bar in the last scene.
Trivia: Spoilers. You can briefly see at one point that Margot's high school mascot is an anthropomorphic catfish. In internet slang, "catfishing" is when someone pretends to be someone else online in order to "lure in" others. This is a very subtle clue to the ending, in which it is revealed that the user "fish_n_chips" was a boy who was "catfishing" Margot online.
Trivia: Contemporary or modern-day altered version of the "BTK" (Bind, Torture, Kill) serial killer - Dennis Rader - who murdered at least ten women from 1974-1991 in the Wichita, Kansas area.

Trivia: John Travolta had to ironically wear old-age makeup to play John Gotti, despite the fact that Travolta was already 3 years older at the time of making this film than Gotti ever lived to be.
Trivia: Dennis Quaid's twin children are seen as extras in the dinner scene. His daughter is the little girl who points at him as he falls out of his chair during his medical attack.
Trivia: Part of what made the Coen Brothers agree to make the film for Netflix was that the traditional studio system just isn't funding films like "The Ballad of Buster Scruggs" the way they used to. Studios are instead focusing much more on big-budget comic-book movies and reboots, or super low-budget ventures like horror films. The Coens found Netflix to be one of the only companies that seemed to understand the project and be willing to fund it. Although co-director Joel Coen did lament that he wishes the film had a traditional theatrical release, as he feels audiences respond to and respect movies in a different way on the big screen.
Trivia: Sonal Chapelle, who portrays Frankie Stone, is the real-life daughter of Dave Chapelle, the actor who portrays her father "Noodles" Stone.

Trivia: It might seem bizarre to make a movie about a 90-year-old drug mule (transporter), but "The Mule" is actually based on the true story of Leo Sharp who became known as the oldest drug mule in the U.S. Whereas Leo Sharp was a World War II veteran, Earl Stone in the movie was a Korean War veteran - and Clint Eastwood ("Earl") really did serve during the Korean War.
