Trivia: Lars requested (demanded) a "Mustang [Boss] 302" from the police to flee the bank robbery. Lars did not specify what year, but 1969-1972 and, possibly, 1973 are relevant to the August 23, 1973 real-life incident. The Mustang 302 was blue and it might seem easy to identify its shade, but that's not the case. Historically, there have been almost 900 colors for the Mustang's paint and there are a variety of blues. "Grabber Blue" was popular when the Mustang 302 emerged, as was "Acapulco Blue."
Trivia: At the very end Paul points at a guy on the street with his finger as a gun just like Charles Bronson did in the 1974 version.
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.
