When Patrick Swayze takes Kelly Lynch to his room, he turns on the radio. The uncredited song playing is "I Sold My Soul to Rock'N'Roll" by the German heavy metal band Bullett, from their 1984 album, "No Mercy".
The band playing at the start of the movie is Cruzados. After the band disbanded, lead singer Tito Larriva formed the band Tito & Tarantula, which is the band that plays at the Titty Twister in the movie From Dusk Till Dawn.
The town in which the film is set is a fictional community "outside of Kansas City" called "Jasper", and as Dalton drives into town, the "Welcome to Jasper" sign is visible. There actually is a Jasper, Missouri, south of Kansas City, and it has numerous rivers running near it (as seen throughout the movie). The movie also alludes to "calling a friend in the FBI in Springfield". Springfield, MO, is just over an hour away from Jasper.
The first movie to be given the "RiffTrax" treatment by comedian Michael J. Nelson, who recorded a downloadable humorous commentary in the vein of Mystery Science Theater 3000 to be played in sync with the movie. Nelson had previously claimed this film was the cheesiest movie ever made in his book "Mike Nelson's Movie Megacheese".
The car the Dalton buys at the used car dealership was a 1965 Buick Riviera - the only year that Buick used the "clamshell" headlight covers for the Riviera. The other car that he drives near the beginning of the movie before picking up his Mercedes Benz & leaving for Missouri is a 1964 Buick Riviera.
The character of Dalton was named after the town of Dalton, GA. The film's writer, David Lee Henry, was passing through and stopped at a local bar. The establishment and its patrons left an impression on him, and as a tribute to the town he named the protagonist Dalton.
