James Best initially turned down playing the role of the Texan because he objected to the profanity in the script. However, he eventually agreed to play the part after he learned that both William Devane and Tommy Lee Jones were attached to the movie. Best put ice cubes under his cowboy hat to convey that his character was always sweating.
Quentin Tarantino named his distributing company, Rolling Thunder Pictures, after this film. Rolling Thunder Pictures released B-movies, cult classics, independent films, exploitation movies, and foreign films. The company went under due to poor sales.
In his 1982 book 'Adventures in the Screen Trade,' William Goldman called an advance screening of this movie "the most violent sneak reaction of recent years... the audience actually got up and tried to physically abuse the studio personnel present among them."
Years later, William Devane talked about his regrets with the film not being a bigger hit, stating that the studio lost confidence in it after a disastrous sneak preview that he and Tommy Lee Jones weren't able to convince/force them to stick with their wider release plan. Devane noted that Warren Beatty "knew how to play the game" when he similarly overcame fierce opposition from Warner Brothers regarding "Bonnie and Clyde" and was able to engineer a re-release that ended up making that film an enormous hit; Devane said "I didn't know how to do that. I still don't know how to do that!"
