Butch Cassidy and the Sundance Kid

William Goldman first came across the story of Butch Cassidy in the late 1950s and researched intermittently for eight years before starting to write the screenplay.[7] Goldman says he wrote the story as an original screenplay because he did not want to do the research to make it as authentic as a novel.[8] Goldman later stated:

The whole reason I wrote the ... thing, there is that famous line that Scott Fitzgerald wrote, who was one of my heroes, "There are no second acts in American lives." When I read about Cassidy and Longabaugh and the superposse coming after them—that's phenomenal material. They ran to South America and lived there for eight years and that was what thrilled me: they had a second act. They were more legendary in South America than they had been in the old West ... It's a great story. Those two guys and that pretty girl going down to South America and all that stuff. It just seems to me it's a wonderful piece of material.[8]

The characters' flight to South America caused one executive to reject the script, as it was then unusual in Western films for the protagonists to flee.[9]

According to Goldman, when he first wrote the script and sent it out for consideration, only one studio wanted to buy it—and that was with the proviso that the two lead characters did not flee to South America. When Goldman protested that that was what had happened, the studio head responded, "I don't give a shit. All I know is John Wayne don't run away."[10]

Goldman rewrote the script, "didn't change it more than a few pages, and subsequently found that every studio wanted it."[10]

The role of Sundance was offered to Jack Lemmon, whose production company, JML, had produced the film Cool Hand Luke (1967) starring Newman. Lemmon, however, turned down the role because he did not like riding horses and felt that he had already played too many aspects of the Sundance Kid's character before.[11] Other actors considered for the role of Sundance were Steve McQueen and Warren Beatty, who both turned it down, with Beatty claiming that the film was too similar to Bonnie and Clyde. According to Goldman, McQueen and Newman both read the scripts at the same time and agreed to do the film. McQueen eventually backed out of the film due to disagreements with Newman. The two actors would eventually team up in the 1974 disaster film The Towering Inferno. Jacqueline Bisset was a top contender for the role of Etta Place.[12]

Filming locations include the ghost town of Grafton, Zion National Park, Snow Canyon State Park, and the city of St. George. These areas remain popular film tourism destinations, including the Cassidy Trail in Reds Canyon.

The world premiere of the film was on September 23, 1969, at the Roger Sherman Theater, in New Haven, Connecticut. The premiere was attended by Paul Newman, his wife Joanne Woodward, Robert Redford, George Roy Hill, William Goldman, and John Foreman, among others.[14] It opened the next day in New York City[1] at the Penthouse and Sutton theatres.[15]

The film became available on DVD on May 16, 2000, in a Special Edition that is also available on VHS.

The film grossed $82,625 in its opening week from two theatres in New York City.[15] The following week it expanded and became the number one film in the United States and Canada for two weeks.[16][17] It went on to earn $15 million in theatrical rentals in the United States and Canada by the end of 1969.[18] According to Fox records the film required $13,850,000 in rentals to break even and by December 11, 1970, had made $36,825,000 so made a considerable profit to the studio.[19] It eventually returned $45,953,000 in rentals.[20]

With a final US gross of over $100 million,[21] it was the top-grossing film released in 1969.

It was the eighth-most-popular film of 1970 in France.[22]

Early reviews gave the film mediocre grades, and New York and national reviews were "mixed to terrible" though better elsewhere, screenwriter William Goldman recalled in his book Which Lie Did I Tell?: More Adventures in the Screen Trade.[23]

Time magazine said the film's two male stars are "afflicted with cinematic schizophrenia. One moment they are sinewy, battered remnants of a discarded tradition. The next, they are low comedians whose chaffing relationship—and dialogue—could have been lifted from a Batman and Robin episode."[24] Time also criticized the film's score as absurd and anachronistic.

Roger Ebert's review of the movie was a mixed 2.5 out of 4 stars. He praised the beginning of the film and its three lead actors, but felt the film progressed too slowly and had an unsatisfactory ending. But after Harriman hires his posse, Ebert thought the movie's quality declined: "Hill apparently spent a lot of money to take his company on location for these scenes, and I guess when he got back to Hollywood he couldn't bear to edit them out of the final version. So the Super-posse chases our heroes unceasingly, until we've long since forgotten how well the movie started.”[25]

Over time, major American movie reviewers have been widely favorable. Rotten Tomatoes gives the film an 88% approval rating based on 52 reviews and an average score of 8.3/10. The site's critical consensus reads: "With its iconic pairing of Paul Newman and Robert Redford, jaunty screenplay and Burt Bacharach score, Butch Cassidy and the Sundance Kid has gone down as among the defining moments in late-'60s American cinema."[26]

The Writers Guild of America ranked the screenplay #11 on its list of 101 Greatest Screenplays ever written.[27]

The film is recognized by American Film Institute in these lists:

• 2008 – AFI's 10 Top 10: Western – #7[38]

In September 2022, Amazon Studios announced a television adaptation of the film, starring Regé-Jean Page and Glen Powell. Joe and Anthony Russo will be executive producers under their AGBO production banner.[41][42]
