Historical basis The basic plot elements of the film were inspired by Wyoming's 1892
Johnson County War, the archetypal cattlemen–homesteaders conflict, which also served as the background for
Shane and
The Virginian. Most of the film's principal characters bear the names of figures in the war but the events portrayed in ''Heaven's Gate'' bear little resemblance to historical events.
Inaccuracies Homesteaders began to settle northern Wyoming in the 1890s, claiming land under the
Homestead Acts, but there were no hordes of starving European immigrants killing rich men's cattle to feed their families, as depicted in the film.
Nate Champion is portrayed as a murderer and "enforcer" for the stockmen, but he was a popular small rancher in
Johnson County, nicknamed "king of the rustlers" by the stockmen because he resisted their tactic of claiming all
unbranded young cattle as their own. There is no evidence that Watson was a bordello madam, as portrayed in the film, nor that Watson or Averell ever knew Nate Champion. A third version of the script was submitted to
20th Century Fox before the release of
The Deer Hunter. His directorial debut,
Thunderbolt and Lightfoot (1974), was a hit. In 1979, on the eve of winning two
Academy Awards (
Best Director and
Best Picture) for 1978's
The Deer Hunter at the
51st Academy Awards, Cimino convinced
United Artists (UA) to resurrect the ''Heaven's Gate'' project with
Kris Kristofferson,
Isabelle Huppert, and
Christopher Walken as the main characters. He was given an initial budget of $11.6 million, but was also provided with
carte blanche. Cimino's girlfriend, Joann Carelli, was hired to produce the film.
Filming Cimino and his friends searched through 20,000 miles of land for scenery for the film.
Principal photography began on April 16, 1979, in
Glacier National Park, east of
Kalispell, Montana, with the majority of the town scenes filmed in the
Two Medicine area, north of the village of East Glacier Park. Shooting also included the town of
Wallace, Idaho. The project had a December 14 projected release date and $11.6 million budget, and promptly fell behind schedule.
Production issues According to legend, by the sixth day of filming the project was already five days behind schedule. An entire tree was cut down, moved in pieces, and relocated to the courtyard in
Oxford, England, where the Harvard 1870 graduation scene was shot. Cimino had an irrigation system built under the land where the major battlefield scene would unfold so that it would remain vividly green, to contrast with the red color. Cimino shot more than 1.3 million feet (400,000 metres; nearly 220 hours) of footage, costing the studio approximately $200,000 per day in salary (equivalent to $720,000 in 2022), locations and acting fees. Privately, it was joked that Cimino wished to surpass
Francis Ford Coppola's mark of shooting one million feet of footage for
Apocalypse Now (1979). As a result of the delays, several musicians originally brought to Montana to work on the film for only three weeks ended up stranded, waiting to be called for shoots to materialize. The experience, as the
Associated Press put it, "was both stunningly boring and a raucous good time, full of
jam sessions, strange adventures and curiously little actual shooting." The jam sessions served as the beginning of numerous musical collaborations between Bridges and Kristofferson.
John Williams turned down the chance to compose the score for the film, which eventually went to
David Mansfield. As production staggered forward, United Artists seriously considered firing Cimino and replacing him with another director, implied in the book
Final Cut to be
Norman Jewison.
Filming completes ''Heaven's Gate'' finished shooting in March 1980, having cost nearly $32 million. Reportedly, during post-production Cimino changed the lock to the studio's editing room, prohibiting executives from seeing the film until he completed his cut, although Cimino disputed this story.
William Reynolds, one of the editors for the film, told
CinemaEditor Magazine in 1991 that he saw problems with the film and wanted the producers to look over the film. Reynolds was instead ignored before being told to "shut up" since they did not have enough time.
Post-production On June 26, 1980, Cimino previewed a
workprint for executives at United Artists that reportedly ran five hours and twenty-five minutes (325 minutes), which Cimino said was "about 15 minutes longer than the final cut would be." The executives flatly refused to release the film at that length and once again contemplated firing Cimino. However, Cimino promised them he could re-edit the film and spent the entire summer and fall of 1980 doing so, finally paring it down to its original premiere length of three hours and 39 minutes (219 minutes). The original wide-release opening on Christmas of 1979 had come and gone, so UA and Cimino finally set up a release date of November 1980. ==Release==
