Continuity mistake: In the bicycle riding scene where Butch lets Etta ride on the handlebars, you can see her feet are resting on some sort of pegs protruding from the axle on each side of the bicycle wheel. When she is not riding, the pegs are not there.

Trivia: In 1981, Robert Redford founded the Sundance Film Festival, which is named after his character the Sundance Kid.
Question: In the final scenes where they are trapped by the Bolivian police in that little room, they're guessing how many men are out there when Butch says, "maybe its only one guy?" Suddenly 3 shots, too quick to be one gunman rings out. Sundance looks at Butch and says. "don't you ever get sick of being right?" Isn't Butch wrong? There's an army out there.
Answer: Sundance is being sarcastic. Butch is a know-it-all, and he's been frequently proven wrong throughout the film, usually to their detriment, but continues to think he's the "smart one" of the duo. Sundance is just ribbing him.
