One of my favourite films from day one.

From Wikipedia:

The final cut of "Heaven's Gate" premiered at New York's Cinema 1 theater on November 19, 1980. The premiere was, by all accounts, a disaster. During the intermission, the audience was so subdued that director Michael Cimino was said to have asked why no one was drinking the champagne. He was reportedly told by his publicist, "Because they hate the movie, Michael."

The initial critical reception was almost universally negative. New York Times critic Vincent Canby panned the film, calling it "something quite rare in movies these days - an unqualified disaster," comparing it to "a forced four-hour walking tour of one's own living room." Canby went even further by stating that "[i]t fails so completely that you might suspect Mr. Cimino sold his soul to the devil to obtain the success of 'The Deer Hunter' (1978) and the Devil has just come around to collect."

After a sparsely attended one-week run, Cimino and United Artists quickly pulled the film from any further releases, completely postponing a full worldwide release.

On April 24, 1981, the film opened in 810 theatres in a "director's cut" two-hour-twenty-nine-minute (149 minute) version that Cimino had recut. Reviewing the shorter cut in the Chicago Sun-Times, Roger Ebert criticized the film's formal choices and its narrative inconsistencies and incredulities, concluding that the film was "[t]he most scandalous cinematic waste I have ever seen, and remember, I've seen 'Paint Your Wagon' (1969)." Kevin Thomas of the Los Angeles Times issued a dissenting opinion when he reviewed the shortened film, becoming one of its few American champions and calling it "a true screen epic" while stating that in two decades as a critic, he had never felt "so totally alone."

The film grossed $1.3 million in its opening weekend and closed after the second week, having grossed only $3.5 million against its $44 million budget.

In 1999, Time placed the film on a list of the 100 worst ideas of the 20th century.

Writing in The Guardian in 2008, Joe Queenan declared 'Heaven’s Gate' the worst film made up to that time. “This is a movie that destroyed the director's career,” he wrote. “This is a movie that lost so much money it literally drove a major American studio out of business. This is a movie about Harvard-educated gunslingers who face off against eastern European sodbusters in an epic struggle for the soul of America. This is a movie that stars Isabelle Huppert as a shotgun-toting cowgirl. This is a movie in which Jeff Bridges pukes while mounted on roller skates. This is a movie that has five minutes of uninterrupted fiddle-playing by a fiddler who is also mounted on roller skates. This is a movie that defies belief.”

In subsequent years, some critics have come to the film's defense, beginning with European critics who praised it after the film played at the Cannes Film Festival. Robin Wood was an early champion of 'Heaven's Gate' and its reassessment, calling it "one of the few authentically innovative Hollywood films ... It seems to me, in its original version, among the supreme achievements of the Hollywood cinema."

David Thomson calls the film "a wounded monster" and argues that it takes part in "a rich American tradition (Melville, James, Ives, Pollock, Parker) that seeks a mighty dispersal of what has gone before. In America, there are great innovations in art that suddenly create fields of apparent emptiness. They may seem like omissions or mistakes at first. Yet in time we come to see them as meant for our exploration."

Martin Scorsese has said that the film has many overlooked virtues. Some of these critics have attempted to impugn the motives of the earliest reviewers. Robin Wood noted, in his initial review of the film, reviewers tended to pile on the film, attempting to "outdo [one an]other with sarcasm and contempt." Several members of the cast and crew have complained that the initial reviews of the film were tainted by its production history and that daily critics were reviewing it as a business story as much as a motion picture.

In April 2011, the staff of Time Out London selected "Heaven's Gate" as the 12th greatest Western of all time. While Peter Biskind covered the many excesses and problems with the movie in his book "Easy Riders, Raging Bulls", he also noted that Heaven's Gate was not dissimilar to other big-budget, troubled projects of the late 1970s and early 1980s (such as Steven Spielberg's '1941" (1979) and Warren Beatty's "Reds" (1981)), and that the backlash against "Heaven's Gate" could have easily been directed elsewhere. Biskind speculated that Cimino's personal unpopularity was the main reason this film became so widely reviled. (Wikipedia)
