Two songs that were originally going to be in the film, but later taken out, were "Shatterproof", a rap song to be sung by Packer during the bar fight scene, and "Don't Be Stupid", a song to be sung by some of the Bingham Canyon miners after the reprise of "Shpadoinkle". An interview with Ian Keldin revealed that Trey thought "Shatterproof" made Packer seem too tough. The film began as a 3-minute trailer made for a film class, having been an idea Parker and his friends had for a while but also inspired in part by Parker's resentment towards his ex-fiancee Lianne Adamo after discovering her cheating on him not long before their wedding, with Packer's disloyal horse "Liane" in the final film being based on her. After the trailer drew much attention, Parker and Stone raised around $125,000 and began shooting the full-length film. The film was shot during weekends and on spring break in 1993, and according to Ian Hardin, most of the crew failed their film history class as a result. Filming was done on location throughout Colorado in Denver, Colorado National Monument, Black Canyon, and Ouray, with the courtroom scenes being shot in the actual courthouse that Alferd Packer was tried in, in Lake City, and the town scenes taking place in Provo, Saguache, and the hanging scene being shot in different parts of the Buckskin Joe Old West theme park in Canyon City. A few incidents happened during filming, such as Parker getting a hairline hip fracture after being thrown from one of the horses playing "Liane", fights occasionally breaking out among the crew, some of the main cast experiencing cold shock and almost being swept away by strong currents from crossing the icy Gunnison River that doubled for the Green River, as well as inclement weather and even an avalanche complicating shooting. This film was originally titled "Alferd Packer: The Musical" in 1993. The film premiered on October 31, 1993, in Boulder, Colorado, at a cinema near the University of Colorado campus. A fake protest organized by friends of Parker and Stone, organized along the lines of an animal rights demonstration, took place in front of the theater. The film then played at Raindance Film Festival in October 2004. Parker and Stone attended. Parker was credited onscreen as Juan Schwartz, a reference to Alferd Packer's alias "John Schwartze", which he was living under when discovered in Cheyenne, Wyoming.
