George Roy Hill’s classic Western made Redford and Paul Newman one of cinema’s iconic duos. Butch (Newman) and Sundance (Redford) are gentleman outlaws, robbing banks and trains across a rapidly civilizing frontier. When things get too hot, they flee to Bolivia, where “you get a lot more for your money”—and get a lot more than they bargained for. Co-starring Katharine Ross (The Graduate) as Redford’s love interest, schoolteacher Etta Place, the film won Oscars for William Goldman’s endlessly quotable script, Conrad Hall’s lyrical cinematography, and Burt Bacharach’s score and original song “Raindrops Keep Fallin’ on My Head,” which accompanies a memorable bicycle interlude. Redford named his Park City film festival after his character here, and Newman’s summer camp for children with serious illnesses shares a name with Butch and Sundance’s Hole in the Wall Gang.
