Lula Parker Betenson, sister of the real Butch Cassidy, often visited the set, and her presence was welcome to the cast and crew. During lulls in shooting, she would tell stories about her famous brother's escapades, and was amazed at how accurately the script and Paul Newman portrayed him.
Before the film was released, the studio found out about her visits and tried to convince her to endorse the movie in a series of ads to be shown in theaters across the country. She said that she would, but only if she saw the film first, and truly stood behind it.
The studio refused, saying that allowing her to see the film before its release could harm its reputation. Finally, at Robert Redford's suggestion, she agreed to do the endorsements, for a small fee.
William Goldman decided to make Etta a teacher because he had seen a photo of the real-life woman, and decided she was too young and pretty to be a prostitute. In fact, most women of that profession in the old West looked haggard, unhealthy, and coarse in the photos he had seen of them.
In the first previews, the audiences went wild with loud, extended laughter, which upset director George Roy Hill, who thought perhaps he had made the film too funny. "They laughed at my tragedy", he said, and re-worked it to take out some of the bigger laughs.
Paul Newman often kidded Robert Redford about his tardiness, once suggesting they should rename the movie "Waiting for Lefty" (Redford is left-handed). "Waiting for Lefty" is a 1935 play by Clifford Odets about a group waiting on the arrival of a man called Lefty, who ultimately never shows up.
In the South America segment, he originally had the characters age to reflect the number of years they spent there, but that was also dropped. "My movie script was darker than the film because of these elements", said William Goldman.
William Goldman first came across the story of Butch Cassidy in the late 1950s and researched it on and off for eight years before sitting down to write the screenplay. He later recalled, "The whole reason I wrote the thing, there is that famous line that F. 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 super posse 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." Goldman said he wrote the story as an original screenplay because he did not want to do the research to make it authentic as a novel.
Before the real Butch Cassidy and The Sundance Kid ended up in Bolivia, they spent some time in the Patagonia area of Argentina, in a town called Cholila. After robbing a bank and fleeing that country, they spent a brief time in Chile, where they befriended miner Percy Seibert, the inspiration for the character Percy Garris.
Two fictional western characters may have been derived from the real Butch Cassidy (1866-1908): Butch Cavendish, the archrival of The Lone Ranger, and good guy Hopalong Cassidy, the film persona of William Boyd.
This movie was the inspiration for the hit TV series Alias Smith and Jones (1971). The actor who played Smith was actually Paul Newman's stand in for this movie: Ben Murphy. Also Smith and Jones were real gunslingers in the wild west who did actually knew Butch Cassidy and the Sundance Kid in real life.
Percy Garris was based on Percy Seibert, a Maryland mining engineer for whom Butch Cassidy and The Sundance Kid worked in Antofagasta, Chile. Contrary to Strother Martin's on-screen death, Seibert was alive when the two died, and served as the coroner's witness.
In a 1930 interview, Seibert reaffirmed having identified the two dead in 1908, and insisted that the "William T. Philips" theory was "rubbish". Conspiracy theorists (nuts) have him lying to the coroner so that his friends could be declared legally dead and start a new life.
Harvey Logan (Ted Cassidy), portrayed as a simple-minded thug, was in fact a suave ladies' man and calculating cold-blooded murderer. He is best known for his clever escape from a jail in Knoxville, Tennessee in 1902.
Like Butch Cassidy and the Sundance Kid, his officially reported death (in a 1904 Colorado train robbery) was contested by mutually exclusive eyewitness claims, which place him simultaneously on several different continents over the following decades.
The men's hairstyles are not appropriate for the 1890s. Their hair is too long in and some are clearly the work of a modern barber using an electric razor.
The female criminal in real life used the name Ethel Place, not Etta. The latter name, used in Pinkerton dossiers and the movie, probably came about as the result of someone misreading someone else's bad handwriting.
During the 27-minute super posse chase, Butch and Sundance dismount and separate from their lone horse, start scaling rocky terrain to evade their pursuers. Butch asks, "What if they don't follow the horse?". Sundance: "Don't worry, Butch, you'll think of something." Originally Butch retorts, "That's a load off my mind."
That line was kept in the movie right through the mid-'70s until it was broadcast on network TV (1976). For some reason it was omitted and has remained absent through every TV, cable, video, laserdisc and previous DVD release. It was reinstated back into the 2006 "Ultimate Collector's Edition" DVD and viewers are treated to it for the first time in 30 years.
